Answer 1

Answer:

568 minutes were used

Step-by-step explanation:

95.16 - 27 = 68.16 ÷ 0.12 = 568 minutes

Answer 2

Nice work on answering parts (a) and (c) correctly.

I'll go over part (b) only.

We replace the C(m) with 95.16 to form the equation

95.16 = 27 + 0.12m

You have the correct equation set up. Your teacher wants you to solve for m.

So,

95.16 = 27 + 0.12m

95.16-27 = 0.12m

68.16 = 0.12m

0.12m = 68.16

m = 68.16/0.12

m = 568

If the student uses exactly 568 minutes, then the cost will be $95.16

Check:

C(m) = 27 + 0.12m

C(568) = 27 + 0.12*568

C(568) = 27 + 68.16

C(568) = 95.16

The answer is confirmed.
