A clothing manufacturer produces coats and slacks. Coats sell for $280, and slacks for $170. Each week, 150 yards of material and 200 hours of labor are available. The material costs $10 per yard, and labor costs $20 per hour. A coat requires 4 yards of material and 10 hours of labor. Slacks require 5 yards of material and 4 hours of labor. How many slacks and coats should be produced each week to maximize profit? Any partially completed slacks or coats can be completed the next week, so fractional solutions are acceptable
