Question

The cost for a long-distance telephone call is $0.36 for the first minute and $0.21 for each additional minute or portion thereof. Write an inequality representing the number of minutes a person could talk without exceeding $3.

Well, Cost= .36 + (minutes-1)(.21)


Does that help?
Yes, that is the correct formula to calculate the cost of a call. Now, we need to set up an inequality representing the number of minutes a person could talk without exceeding $3.

Let m represent the number of minutes talked. So, the inequality should look like this:

0.36 + (m - 1) * 0.21 ≤ 3
