The cost of the phone contract will be mathematically given as
C = 45 + 13m
This is further explained below.
<h3>
What is the formula?</h3>
Generally, According to the information provided, the monthly cost of the fixed line rental is £45, and the price of calls made is £13, thus the monthly cost will be represented by the following:
C = 45 + (13 × m)
Therefore
C = 45 + 13m
As a result, the price of the phone contract will be equal to C = 45 plus 13m, where m is the number of months in the contract.
