Question

Dear library patrons:

To ensure that all visitors have the opportunity to use our limited number of computers, we ask that each person restrict himself or herself to 30 minutes on a computer. For those needing to use a computer beyond this time frame, there will be a $3 charge for each 15-minute period.
We thank you in advance for your cooperation.

Pineville Library

Raoul has an upcoming school project, and his own computer is not working. He needs to use the library computer, and he has estimated that he will need to be on the computer for approximately an hour and a half. How much of a fee can Raoul expect to pay for his computer use at the library?
a. $6
b. $9
c. $12
d. $15

Answer 1

Raoul will have to pay for an hour, which is divided into four 15-minute periods at $3 each, totaling $12.

Step-by-step explanation:

Raoul needs to use the Pineville Library computers for his school project. He is allowed 30 minutes for free, and since he needs the computer for an hour and a half, he will have to pay for an additional hour.

The library charges $3 for every 15 minutes after the initial 30 minutes.

To calculate the fee, we divide the additional hour into 15-minute periods.

Number of 15-minute periods in an hour: 60 minutes / 15 minutes = 4 periods.

Cost for each period: $3.

Total fee = 4 periods x $3/period = $12.

Therefore, Raoul can expect to pay a fee of $12 for using the computer for an hour and a half.
