Question

A parking garage charges ​$1.50 for the first hour and ​$0.75 for each additional hour. If a customer gave the parking attendant ​$45 for parking from 10 A.M. to 3 P.M.​, how much did the garage​ charge?

Answer 1

The garage charged $4.50

Explanation:

The equation for this problem is:

Bill=Cost first hour + (x-1) × Cost aditional hour ("x" is the total amount of hours)

Total amount of hours: 5 hours

So,

Bill=$1.50+(x-1)×
`(0.75)/(hour)`$= $1.5+(5 hour-1 hour)×
`(0.75)/(hour)`$=$4.50
