a cellular phone company charges $.45per minute plus a $25 monthly fee. how do you write the equation to determine the cost for the month
The cost (c) for (m) minutes is:
c = $25.00 + .45m
If you think on it a minute, you'll see why this is so.
To determine the monthly cost for a cellular phone plan that charges $0.45 per minute and includes a $25 monthly fee, you can write the equation as follows:
Cost = ($0.45 * Minutes) + $25
In this equation, "Minutes" represents the total number of minutes used in a month. Multiply the per-minute charge ($0.45) by the number of minutes used, and then add the $25 monthly fee to find the total cost for the month.
