Question 437244: Your boss has asked you to come up with a price model for one of the cell phone models that your company produces. In the model, costs and length of service are directly related. You are also asked to examine the profit formula based on selling a certain number of the phones to determine profitability based on how many are sold.
Suppose a cell phone service costs $45 per month, along with a $60 activation fee.
Write a cost equation that relates the number of months of service and the total cost for that time of service. (Hint: Let t = the number of months of service and c = the total cost.)
Use the cost equation to determine the number of months of service for a cost of $1,185.

You can put this solution on YOUR website! Suppose a cell phone service costs $45 per month,
along with a $60 activation fee.
---------------------------------------
Write a cost equation that relates the number of months of service and the total cost for that time of service. (Hint: Let t = the number of months of service and c = the total cost.)

Ans: C(x) = 60 + 45x where x is # of months of service.
-----------------------------------------------------------------
Use the cost equation to determine the number of months of service for a cost of $1,185.

1185 = 60 + 45x
45x = 1125
x = 25 months.
