A long-distance telephone plan costs $2.00 a month, plus 4 cents per minutes, or part thereof, for any long-distance call made during the month.

Write a verbal rule to determine the total monthly cost for your long-distance calls for the month.

Two dollars plus four cents times number of minutes.

The verbal rule to determine the total monthly cost for your long-distance calls for the month would be:

To calculate the total monthly cost for your long-distance calls, you need to add together the base cost of $2.00 and the cost for the number of minutes you used. Multiply the number of minutes by 0.04 (4 cents per minute) and then add that result to the base cost of $2.00. That sum will give you the total monthly cost for your long-distance calls.
