Question

A parking lot costs $1300 a month to operate, and it spends $260 each

month for every car that parks there. The parking lot charges a monthly fee of
$450 to park a car. If n is the number of cars, which equation represents the
profit function of the parking lot?
A. p= 710n+ 1300
B. p = 710n- 1300
c. p= 190n - 1300
D. p= 190n + 1300
SUBMIT
A

Answer 1

`p = 190n - 1300`

Explanation:

Given

`Monthly = 1300`

`Expenses = 260` per car

`Charges = 450` per car

Required

Determine the profit

Let the number of cars be n. So:

Express on n cars is: 260n

Charges on n cars is 450n

The profit (p) is then represented as:

`p = Charges - Expenses - Monthly\ Expenses`

`p = 450n - 260n - 1300`

`p = 190n - 1300`
