The cost c in £ of a monthly phone contract is made up of the fixed line rental l in £ and the price p in £ of the calls made. enter a formula for the cost and enter the cost if the line rental is £35 and the price of calls made is £12

The cost of the phone contract will be C = 35 + 12m.

From the information given, the fixed line rental is £35 and the price of calls made is £12, therefore the monthly cost will be represented by:

C = 35 + (12 × m)

C = 35 + 12m

Therefore, the cost of the phone contract will be C = 35 + 12m where m represents the number of months.

the formula for the cost is

c = l + p

Total cost is £47

Step-by-step explanation:

Let c represent the cost in £ of a monthly phone contract made up of the fixed line rental l in £ and the price p in £ of the calls made.

The formula for the cost, c would be

c = l + p

if the line rental is £35 and the price of calls made is £12, then, the total cost, c would be

c = 35 + 12 = £47
