Question

A parking lot costs $2100 a month to operate, and it spends $130 each

month for every car that parks there. The parking lot charges a monthly fee of
$360 to park a car. If n is the number of cars, which equation represents the
profit function of the parking lot?

Answer 1

$230n-$2100

Explanation:

Profit=revenue-cost

Cost=$2100+$130×n

Revenue=$360×n

Profit=$360n-($2100+$130n

=$360n-$2100-$130n

=$230n-$2100
