You can put this solution on YOUR website!
x of the 30 pack
y of the 80 pack
both must be positive whole numbers.
30x%2B80y=250
3x%2B8y=25


graph%28300%2C300%2C-2%2C10%2C-2%2C10%2C-3x%2F8%2B25%2F8%29

Easier to pick values for y and find which x will work.
3x=25-8x
system%28y=2%2Cx=3%29

3 of 30 each and 2 of 80 each
