The sum of the adult and youth shirt revenues needs to equal $489. Let's break this down further so we can see the correct answer.

The Prices of the Shirts and Total Earnings

To begin, remember the essential details: adult shirts are priced at $15 each, youth shirts cost $12 each, and the combined earnings totaled $489. Each component of the total earnings plays a key role in framing the proper equation. The price per shirt and the number sold are the variables that determine the equation's structure. Understanding the pricing system of your T-shirt shop is important because it dictates how we should write the equation. The fundamental concept here is creating an equation that can accurately predict sales and track earnings based on the number of shirts sold. You have to consider the relationship between the prices of the shirts and the total money earned. When we're crafting the equation, we're not just creating a math problem; we're essentially building a mini-model of how your business operates. The final earnings reflect the combination of adult and youth shirts that were sold. This is what we are trying to uncover, and the equation should guide us to the correct answer. The task is to carefully analyze the relationship between the individual prices of the shirts, the quantities sold, and the total revenue. This is a great exercise for improving math and analytical skills. The total earnings are the crucial point that needs to be expressed correctly by the equation. A correct approach is to represent each component of the total revenue with an expression and then combine them to get the total. This process demonstrates the fundamental skill of translating a real-world scenario into an algebraic expression. Therefore, the task requires meticulous attention to the details of the problem statement and the ability to formulate an accurate equation. To successfully tackle this problem, you need to be precise, understanding each detail and then representing it mathematically.

This process of figuring out the equation allows you to reflect on what you already know and apply it to a new situation. The goal is to build an accurate equation to understand the relationship between the number of shirts sold and the total sales.

The Core of the Equation: Translating Words into Math

Now, let's translate the word problem into a mathematical equation, the heart of our solution, right? We know each adult shirt sells for $15, and we're calling the number of adult shirts 'x'. So, the total money made from adult shirts is 15x. Similarly, each youth shirt sells for $12, and we're calling the number of youth shirts 'y'. Therefore, the total money made from youth shirts is 12y. The total earnings from both types of shirts combined equal $489. So, our equation should reflect: (earnings from adult shirts) + (earnings from youth shirts) = $489. This setup gives us the correct expression and enables us to solve the problem by representing a real-world situation mathematically. Therefore, the accurate equation representing the situation is 15x + 12y = 489. We successfully translated the word problem into an equation. Now, understanding what each component represents is crucial. '15x' represents the total revenue generated from the sale of adult shirts. '12y' stands for the total income from youth shirts. The sum of these two components gives us the overall revenue of $489, which the T-shirt shop collected. It is essential to recognize the real-world meaning behind each component in the equation. 'x' denotes the quantity of adult shirts, 'y' denotes the number of youth shirts, and the equation tells us the total earnings are the result of adding the revenue from adult and youth shirts. This understanding is key for correctly representing the situation mathematically. The equation is a simple yet powerful tool for calculating and forecasting sales. It allows you to model business operations by showing how the price and quantity of each item directly affect your overall revenue. Moreover, the equation becomes a solid base for various other business calculations. The equation is the starting point for exploring more advanced analyses, like calculating profit margins, adjusting prices, and predicting future revenue. The ability to use this equation is the first step toward more complex business decisions. It can be used to optimize sales strategies. For example, if you know the number of youth shirts sold (y), you can easily solve for 'x' to find out how many adult shirts were sold. It's a key part of understanding the relationship between the different components of your T-shirt shop's sales.

The Correct Equation: 15x + 12y = 489

Therefore, the correct equation that represents the situation is 15x + 12y = 489. This equation directly correlates the total earnings with the number of adult and youth shirts sold. It allows you to calculate the total amount of money earned by the T-shirt shop from its shirt sales. By knowing the value of 'x' or 'y', you can derive the other, allowing us to find multiple combinations of adult and youth shirts that could have resulted in $489 in total earnings.
