    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
