At 8:15 AM, Maya 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 bought 15 minutes of parking time, at what time would the meter expire?: *
A) 11:20 AM
B) 11:35 AM
C) 11:50 AM
D) 12:00 PM
B) 11:35 AM
Maya put a total of 45 cents into the meter (5 cents + 10 cents + 25 cents + 5 cents). This means she bought 135 minutes of parking time (15 minutes for every 5 cents).
Since the meter had 20 minutes left until it expired when Maya found it, the total parking time would be 135 minutes + 20 minutes = 155 minutes.
Adding 155 minutes to the initial time of 8:15 AM, we get 11:30 AM. Therefore, the meter would expire at 11:30 AM + 5 minutes = 11:35 AM.
