At 8:15 AM, Emory found a parking meter that still had 20 minutes until it expired. She quickly put a nickel, a dime, and two quarters in the meter and went shopping. If every 5 cents buys 15 minutes of parking time, at what time will the meter expire?

A) 11:20 AM
B) 11:35 AM
C) 11:50 AM
D) 12:00 PM

1 answer

To calculate the total parking time purchased, we first need to determine how much time each coin buys:

- 1 nickel = 5 cents = 15 minutes
- 1 dime = 10 cents = 30 minutes
- 1 quarter = 25 cents = 75 minutes

So, Emory's total payment of a nickel, a dime, and two quarters buys:
5 minutes + 30 minutes + 75 minutes + 75 minutes = 185 minutes

To find out when the meter will expire:
- 8:15 AM + 185 minutes = 11:20 AM

Therefore, the meter will expire at 11:20 AM, which corresponds to option (A).
