Consider a vegetable Farm problem: Each square metre of Arugula uses 14 hours of weeding and 6 hours of harvesting; each square metre of Bok Choy uses 6 hours of weeding and 4 hours of harvesting. (Arugula is a leafy green vegetable; Bok Choy is related to cabbage.) You have 140 hours of weeding and 80 hours of harvesting available. Revenue is $24/Arugula square metre and $10/Bok Choy square metre, and you want to maximize revenue. Set up and solve this LP by hand. Answer this question and then continue with the True/False questions that also pertain to this model. What is the revenue at the optimal solution? Just type the value, e.g., 400. Do not include a dollar sign, units, or other characters. Do not include decimals.
