Again, everything you have studied up tp this point IS your start on the problem. Use what you know. It is NOT an entirely new experience.

Answer these questions:

1) How much did the call cost? You need subtraction.

2) Units will reveal the rest. You have $$. You are given ¢/minute. Division will give minutes.
