Answer:
$14,600
Step-by-step explanation:
The function P(a) = 25,000a - 1000 gives the amount of potatoes, P, in kilograms, that he expects to produce from planting potatoes on a acres of land.
If Ben plants on 3 acres of land, then the amount of potatoes expected will be:
P(3) = 25,000(3) - 1000 =74,000kg
The amount of money, M, in dollars, that Ben expects to make if he produces p kilograms of potatoes is given by the function:
M(p) = 0.2p - 200
Since Ben produces 74000kg on 3 acres, the amount of money he is expected to make is then:
M(74000) = 0.2(74000) - 200
=$14,600
Ben will make $14,600 if he sells all of the potatoes produced on the 3 acres.
