A parking garage charges $1.50 for the 1st hour of parking and $0.75 for each additional hour. What is the cost in dollars for parking 7 hours? Show your work.
The equation you have to solve is 1.50 + (0.75 • 6). First, you solve what is in the parenthesis, 0.75 • 6 = 4.50. Now you simply add 1.50 and 4.50 to get $6, the total cost for 7 hours worth of parking.
