Question

A pre-paid cell phone company charges $10.4 as a monthly access fee and $0.18 per minute of calling time. Express the monthly cost C in terms of minutes of call time. What will the monthly cost be if you make 315 minutes of calls this month?

Answer 1

Answer:$67.10

Step-by-step explanation:

Using the first statement we can generate the equation c= 0.18m + 10.4  where c is the cost and m is the number of minutes. So if you make 315 minutes of call then input  that for m and solve for c.

c= 0.18(315) + 10.4

c= 67.10
