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 = [tex] 190 \times \$ 0.25 [/tex]

= 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
