Hello,

c is the amount of caps

v is the amount of visors

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

First rearrange your equation:

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 ...

tschüss
