1 quarter + 1 dime + 1 nickel = 25¢ + 10¢ + 5¢ = 40¢
Each 5¢ buys 15 minutes. How many ' 5¢ ' are in 40¢ ?
40/5 = 8 of them. So the (quarter+dime+nickel) can buy 8 x 15 minutes = 2 hours.
Starting at 9:00 AM, the meter had 5 minutes left on it, and Marsha bought
another 2 hours. So now the meter is good until 2 hours and 5 minutes
after 9:00 AM . . . . . 11:05 AM.
