At & T has a cell phone plan of $25.00 a month plus 30 cents per minute. There is a one year contract wit a new phone for $19.99

Can someone put this into a equation for me.

19.99 / 12(months in a year) =

Then you would compare it to see which one is a better plan. The 30 seconds per min. isn't important.

Sure! To put this situation into an equation, let's use the following variables:

C = total cost
M = number of minutes used

Based on the given information, the total cost would consist of three elements: the monthly fee of $25.00, the additional cost per minute of 30 cents, and the one-time cost for the new phone of $19.99. The equation can be written as:

C = $25.00 + $0.30M + $19.99

This equation represents the total cost (C) as a function of the number of minutes used (M). By plugging in the value for M, you can calculate the total cost.
