Find the equations to: Alice spent $131 on shoes. Sneakers cost $15 and Fits cost $28. If she bought a total of 7 shoes, then how many of each kind of shoe did she buy?
Let x = Sneakers
Let y = Fits
Our first equation based on price is:
15x + 28y = 131
The second equation based on number is:
x + y = 7
