Question

A city bus charges $0.25 per ride if you first buy the $10 discount card. Let B be the total cost, in dollars, of taking n rides on the bus.

Answer 1

`B= 10 + 0.25n`

Explanation:

Given

`Base\ Amount = \$10`

`Charges = \$0.25` per ride

Required

Calculate total cost, B

If 1 ride costs $0.25

n rides would cost $0.25 * n

n rides = $0.25n

Total Cost is then calculated as:

`B = Base\ Amount + Rides`

Substitute values for Base Amount and Rides

`B= 10 + 0.25n`
