Nov 4, 2025 by Andrew McMorgan 48 views

Hey Plastik Magazine readers! Ever wondered how online shopping costs really stack up? Today, we're diving into a real-world scenario with Glenda, who's been busy sprucing up her space. She's just made an online purchase, and we're going to break down all the numbers to see exactly how much she's spent. This is a great way to understand how online shopping calculations work, including things like taxes and shipping – crucial stuff, right? We'll use this example to illustrate the process, making it easy to understand for everyone. Get ready to put on your financial detective hats, because we are getting into some cool maths! It's all about making smart choices when you shop online, and understanding the costs involved is the first step towards doing just that. Ready to crunch some numbers? Let's get started!

The Initial Purchase: Frames and Mats

First off, Glenda's picked out some lovely picture frames and mats. She's gone for four frames, each priced at $ $12.95$ $. Then, to complete the look, she's added four mats, with each one costing $ $5.89$ $. So, to kick things off, we need to calculate the cost of the frames and the cost of the mats separately. This is a pretty straightforward calculation – just simple multiplication. For the frames, we multiply the number of frames by the price per frame, and for the mats, we do the same. This gives us the subtotal cost for these items before we even think about tax or shipping. Knowing the initial cost of the items is the foundation of understanding the total cost of her purchase. Are you ready to dive into the mathematical fun? We are going to reveal the first part of this equation. So, let’s begin our mathematical journey! Keep in mind these small steps so that we can clearly understand the purchase costs. Because at the end, we want to know how much Glenda spent, right? Let's break it down, step by step, so even the most math-averse person can follow along. It is going to be super easy, and at the end of this section, we'll see exactly how much she spent on those picture frames and mats.

Frame Cost Calculation

Alright, let's get down to brass tacks. Glenda snagged four picture frames, and each one was priced at $ $12.95$ $. To figure out the total cost for the frames, we simply multiply the number of frames (4) by the price per frame ($ $12.95$). So, the calculation looks like this: $4 \times $$12.95 = $ $51.80$ $. This means Glenda spent $ $51.80$ $ on the picture frames. See? Easy peasy! We've taken the first step in understanding the cost of Glenda's purchase. This is a good example of how even small purchases can add up, so it's always useful to keep track of these things. Now, with the frames sorted out, we can move on to the mats. Ready to see how much she spent on those too? Let's dive in!

Mat Cost Calculation

Next up, we need to calculate the cost of the mats. Glenda bought four mats, each priced at $ $5.89$ $. The math here is very similar to what we just did for the frames. We're going to multiply the number of mats (4) by the price per mat ($ $5.89$). The calculation is: $4 \times $$5.89 = $ $23.56$ $. That means Glenda spent $ $23.56$ $ on the mats. Pretty simple, right? Now we have the cost for both the frames and the mats. This is the subtotal – the cost of the items before we add in any other charges. Now that we know how much Glenda spent on frames and mats individually, it's time to find out the combined cost. Are you ready to move on to the next step?

Subtotal Calculation: Frames + Mats

Okay, now that we know the individual costs of the picture frames and the mats, the next step is to combine them to find the subtotal. This is the total cost of the items Glenda purchased before taxes and shipping. To calculate the subtotal, we simply add the cost of the frames to the cost of the mats. So, from the previous calculations, we know the frames cost $ $51.80$ $, and the mats cost $ $23.56$ $. Therefore, the subtotal is $$51.80 + $$23.56 = $ $75.36$ $. So, the subtotal for Glenda's purchase is $ $75.36$ $. This is the base amount upon which the taxes will be calculated. It's a key step in understanding the final cost, as it sets the stage for calculating the taxes and shipping charges. It is like the foundation of a house; without it, the rest cannot stand. Now, let’s move on to the next section and learn about taxes.

Tax Calculation: A Percentage of the Subtotal

Here’s where things get a little more interesting! The website states that taxes are $ $6.5\%$ $ of the total purchase price. This means we need to calculate $ $6.5\%$ $ of the subtotal (which we just found to be $ $75.36$ $). To calculate a percentage of a number, we first convert the percentage to a decimal by dividing it by 100. So, $ $6.5\%$ $ becomes $ $0.065$ $. Then, we multiply this decimal by the subtotal. The calculation is: $$75.36 \times 0.065 = $ $4.8984$ $. Rounding this to the nearest cent (as is standard practice), the tax amount is $ $4.90$ $. Taxes are a significant part of the total cost, so it's important to understand how they are calculated. The tax is added to the subtotal to give us a new subtotal. Ready to go to the next step, where we are going to add this tax to our existing subtotal?

Shipping Charges: The Final Piece

Alright, let’s talk about shipping! This is the final cost we need to consider. The problem doesn't give us the shipping price, so let's assume the shipping charges are $ $10$ $. This is a common practice in online shopping. You'll often see the shipping cost listed separately. Let's make the math very easy! Knowing how to calculate shipping costs is super important because it can significantly impact the final price. We are not given any specific formula to calculate this, but we will add the value to the final price. Remember, shipping costs can vary depending on the vendor. The shipping price, as we said, is $ $10$ $. So, with our tax and shipping figured out, we can determine the final price.

Calculating the Total Cost

Now, let's put it all together to calculate the final total. We have the subtotal (the cost of the frames and mats), the taxes, and the shipping charges. The subtotal was $ $75.36$ $, the taxes are $ $4.90$ $, and the shipping is $ $10$ $. To find the total cost, we add all these amounts together: $$75.36 + $$4.90 + $$10 = $ $90.26$ $. Therefore, the total cost of Glenda's purchase, including frames, mats, taxes, and shipping, is $ $90.26$ $. That’s the grand total! Understanding these individual costs helps you make smart purchasing decisions. It helps you compare prices and choose the best deals! And there you have it, folks – a complete breakdown of Glenda's online shopping costs! You can use this example to understand your own online purchases! Let's summarize the whole calculation, starting from scratch. First, we calculated the cost of the frames and the mats separately and then, the subtotal. After that, we calculated the taxes and the shipping charges and, finally, we added everything together to find the final price. Remember that knowing how to break down the cost will help you better understand your own spending habits and shop smarter. So next time you are shopping online, keep these steps in mind. Keep your eyes peeled for those shipping costs, and always check the tax. We hope this was a useful, easy-to-follow guide to online shopping calculations. This is how you calculate total cost when you are shopping online, and always keep an eye on how much you are spending! Happy shopping, everyone!
