Answer:
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.
- x = number of $15 packages sold
- y = number of $20 packages sold
- The school collected $4250 from sales
- 250 packages were sold in total
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.
