A fruit grower raises crops A and B. The yield is 300 bushels per acre for crop A and 500 bushels per acre for crop B. Research and available resources indicate the following constraints.

The fruit grower has 150 acres of land available.
It takes 1 day to trim the trees on an acre of crop A and 2 days to trim an acre of crop B, and there are 240 days per year available for trimming.
It takes 0.3 day to pick an acre of crop A and 0.1 day to pick an acre of crop B, and there are 30 day per year available for picking.
What is the optimal acreage for each fruit? What is the optimal yield?
