Answer:

Cost of cultivating crop A and crop B = 40A + 60B <= 7400

Labour/hour= 20A + 25B <= 3300

Maximum profit = l80A + 200B

Explanation:

Cost of cultivating crop A<= $40/acre

Cost of cultivating crop B <= $60/ acre

The farmer has a maximum of $7400 for cultivating

Total cost = 40A + 60B <= 7400

Each acre of crop A require 20 labour- hour

Each acre of crop B require 25 ls our- hour

The farmer has a maximum of 3300 labour- hours

Total labour hour= 20A + 25 B <= 3300

If the farmer expects to make profit of $18₩/acre on crops and $200/acre on crop B,

His maximum profit P= 180A + 200B
