A clothing manufacturer has 100m of silk and 180m of wool. To make a suit requires 2m of silk and 3m of wool, and to make a dress requires 1m of silk and 2m of wool. If the profit on a suit is $108 and the profit on a dress is $60, how many suits and dresses should the manufacturer make to maximize the profit?
I can't seem to get it. I tried the following but I get stuck big time:
silk = 100 m
wool = 180 m
suit = 2 meters of silk and 3 meters of wool
dress = 1 meters of silk and 2 meters of wool
profit = (108)*(# of suit sold) + (60)*(# of dress sold)
