<PRE><B>Question 437244</B>
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.
