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.

Answer:
The two numbers are <em>32</em> and <em>60</em>.
Step-by-step explanation:
We can create two simultaneous equations to solve this problem using the information given in the question.
Let number 1 = x
Let number 1 = y
x = y - 28 -> ( 1 )
x + y = 92 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.
Substitute ( 1 ) into ( 2 ):
x + y = 92 -> ( 2 )
( y - 28 ) + y = 92
2y - 28 = 92
2y = 120
y = 120 / 2
y = 60 -> ( 3 )
Substitute ( 3 ) into ( 1 ):
x = y - 28 -> ( 1 )
x = ( 60 ) - 28
x = 32
Therefore:
x = 32 , y = 60
