ABC Telephone has a special long distance telephone rate. The first 10 minutes of a call cost $0.15 per minute. Each additional minute is only $0.05 a minute. How much would a 35-minute call cost?

First you're going to subtract 35-10 to get 25, which you then have to calculate how many minutes you have left.
The amount you currently owe is 10(0.15), which will give you 1.5. So you currently owe $1.5 for calling 10 minutes.

Next, we have to figure out how much the remaining 25 minutes cost you. That is 25(0.05). The answer to that is $1.25.

Now, add up $1.5 + $1.25 and you will get your answer, which is $2.75!

A 35-minute call would cost $2.75.
