Question

A student's cell phone plan has a monthly charge of $40 for 600 minutes of use and a $0.25/minute charge for each additional minute. Last month, the student talked on the phone for 790 minutes. Which of the following is the bill for the month?

Answer 1

$87.50 because there are 190 minutes over, each minute being .25 cents. which is $47.50. added to the original charge of $40 for 600 minutes

Answer 2

We have to find the bill for this month.

Since, the student talked on phone for 790 minutes.

600 minutes are provided in a monthly charge of $40 and the remaining minutes are charged $0.25/minute.

So, 790 - 600 =190 minutes.

So, 190 minutes are minutes at $0.25/minute.

So, Cost applied on 190 minutes =
`190 * \$ 0.25`

= 47.50

So, Total bill for 790 minutes =

Cost for 600 minutes + Cost for 190 minutes

= $40 + $47.50

= $87.50

So, the bill for the month is $87.50
