Government restrictions limit acreage of crop A to 15 acres, but do not limit crop B. Crop A will take 15 hours of labor per acre at a cost of $5.60 per hur, and crpo B will require 10 hours of labor per acre at $5.00per hour. IF the expected income from crop A is $600 per acre and from crop B is $520 per acre, how many acres of crop A should be planted in order to maximize profit?

Please help me set this up. I am no good with word problems!
