Okay, I may be bad at optimization problems, but this question I can't even read it without getting a headache, and I have a test!!
If a farmer digs up his potatoes on July 1st, the crop is 120 m^3, which sell as new potatoes at $3.00/ m^3. If the crop is allowed to mature further, it increases at 15 m^3/ week. However, the price drops 20 cents/m^3/ week. When should the farmer dig the crop for the maximum cash return??
So am I supposed to find the profit or something or the day hes supposed to dig it up aghhhh
