Data from Example 3

A farmer owns a 100-acre farm and plans to plant at most three crops. The seed for crops A, B, and C costs $40, $20, and $30 per acre, respectively. A maximum of $3,200 can be spent on seed. Crops A, B, and C require one, two, and one work days per acre, respectively, and there are a maximum of 160 work days available. If the farmer can make a profit of $100 per acre on crop A, $300 per acre on crop B, and $200 per acre on crop C, how many acres of each crop should be planted to maximize profit?

Seed cost Work days Profit Investment per Acre Crop B $40 2 $200 Crop A $24 1 $140 Crop C $30 2 $160 Maximum Available $3,600 160
