An illustration of the letter 'A' in a speech bubbles

`m=` number of medium pizzas

`l=` number of large pizzas

Since medium pizza costs $5 and large costs $8 you have $40 to spend your equation is

`5m+8l=40`  

Note that both `m` and `l` must be positive integers. 

Possible solutions are `(m,l)=(8,0)` and `(m,l)=(0,5).`
