Question

A parking meter charges $2 per hour. as a driver parks her car, she notices that the parking meter has 15 minutes remaining on it from the previous driver who used the parking spot. if the driver inserts d dollars into the parking meter and the parking meter has 3 hours remaining on it as a result, which of these equations can be used to solve for d?
A. 3=0.5d+0.15
B. 3=0.5d+0.25
C. 3=2d+0.15
D. 3=2d+0.25

Answer 1

The parking meter charges $2 per hour, means that each half hour costs $1.

Thus, 1$ pays for half an hour, so d $ pay for d half hours, that is d/2 hours, which is 0.5d hours.

15 minutes a quarter of an hour, which is 0.25 h.


Thus, the driver has a total of d/2 hours that she payed for, + 1/4 hour from the previous driver. These make a total of 3 hours, so we can set the equation:

3=0.5d+0.25
