The senior class at Ron’s school collected $4250 from students during picture sales at prom. Some students bought $15 packages and others bought $20 packages. In all, 250 packages were sold. Which system of equations could be used to determine x, the number of $15 packages sold and y, the number of $20 packages sold?

Given the following information, your system of equation is going to be...

x + y = 250

15x + 20y = 4250

Step-by-step explanation:

So, in the problem, we are given important key details that can help us solve it.

Now that we have this information, we can solve the problem. Since 250 packages were sold in total, then you are going to add x and y. Since the school collected $4250 from the sales, then you are going to be adding 15x and 20y together.

So, to conclude, your answer is going to be the first answer choice.
