A farmer has 100 acres on which to plant two crops. The cost of planting the first crop is $20 per acre and the second crop is $40 per acre, and up to $3000 is available to cover the cost of planting. Each acre of the first crop will require 5 work-hours for harvesting and each acre of the second crop will require 20 work-hours. The farmer can rely on having only a total of 1350 work-hours for harvesting the two crops. If the profit is $100 per acre for the first crop and $300 per acre for the second crop, determine the acreage that should be planted with each crop in order to maximize the total profit.
