[gentoo-user] program to solve assignment problem?

[Erik]

Is there some simple little program to solve assignment problems?
Suppose that someone bought k meat (160), m fish (30) and n milk (15)
for 700. So it should solve the equation k * 160 + m * 30 + n * 15 =
700. (A solution happens to be k = 4, m = 2, n = 0. An additional
condition could be that he bought at most 6 items; k + m + n <= 6. That
would eliminate solutions like k = 4, m = 0, n = 4.)
