Hello,

c is the amount of caps
v is the amount of visors

Then you get the equation: 3*v + 7*c = 4480

7*c = 4480 - 3*v
c = 640 - 3/7*v

c and v must be integer numbers (a half cap looks quite funny!)

Therefore v must be a multiple of 7 so that you can simplify 3/7*v to an integer number.

the first possible number for v is 7.

Code:
v    7    14    21    28    ...
c    637  634  631   628    ...
tsch&#252;ss
