Question

A prepaid cell phone company charges 13.5 as a monthly fee and 0.19 per minute of calling Time express the monthly cost in terms of minutes of call time

Answer 1

Answer: 71.1minutes

Explanation:

From the question, we were given monthly cost of calls and amount of call per minute.

To express the monthly cost in terms of minutes of call time will be :

Monthly cost = call per minute x f

Let minutes of call time be f

13.5= 0.19 x f

13.5 = 0.19f ....divide both sides by 0.19

f = 13.5/ 0.19

f= 71.1 minutes
