Aparking 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?

The garage charged $4.50

Step-by-step 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=$1.50+(x-1)×$= $1.5+(5 hour-1 hour)×$=$4.50
