Question

An athletic director wants to buy soccer balls and footballs. Each soccer ball costs $15. Each football costs $20. The director can spend no more than $150 in all. Write an inequality to model the situation, where x is the number of soccer balls and y is the number of footballs.

Answer 1

15x + 20y = 150

Explanation:

15x is how many soccer balls he can get and 20y is how many footballs he can get. (I don't know how to explain my thinking.)
