Answer:
4 acres of wheat and 4 acres of rye.
Step-by-step explanation:
Given: Farmer has only 7 acre, he has plant at least 7 acres.
Farmer has only $1200 to spend.
Each acre of wheat will cost $200 and rye will cost $100.
Planting time is only 12 hours
Wheat planting take 1 hour per hour and rye take 2 hours per acre.
Profit on wheat is $500 per acre and rye $300 per acre.
As to find out maximum profit, we need to plant maximum wheat.
While dividing number of acres of land for wheat and rye for plantation, we need to keep two constraint in the mind; Constraint of cost and time as given.
Lets assume few number considering these constraint to get maximum profit.
First assumption, 5 acres of wheat and 2 acres of rye
Time taken=
Total time taken 7 hours
Amount spent=
Total cost is $ 1200.
Profit=
Maximum profit= $3100.
Second assumption, 4 acres of wheat and 4 acres of rye.
Times taken=
Total time taken is 12 hours
Amount spent=
Total cost is $1200.
Profit=
Maximum profit= $3200.
