I can't scan my homework though.
Can I post a problem manually for no points

Anyway, here is one of my homework problems:
In how many ways can you sell $5 and $3 pumpkins to make $200?
It's a diophantine equation. Let x=#of $5 pumpkins, and y=# of $ 3 pumpkins.

Solve for x,

So y must be a multiple of 5. It goes up to until 40-3y/5 is negative.
