POSSIBLE POINTS: 6.3 A farmer feeds his cows a feed mix to supplement their foraging. The farmer uses two types of feed for the mix. Corn feed contains 100 g protein per kg
and 750 g starch per kg. Wheat feed contains 150 g protein per kg and 700 g starch per kg. Each cow should be fed at most 7 kg of feed per day. The
farmer would like each cow to receive at least 650 g protein and 4000 g starch per day. If corn feed costs $0.40/kg and wheat costs $0.45/kg, then what is
the optimal feed mix that minimizes cost? Round your answers to the nearest gram (round to two decimal places as needed.)
