y = 7.5x+45

Step-by-step explanation:

Let your data consumption in terms of GB be represented by x. Since you must first pay access fee and each data costs $7.5 per GB then it means in case you need 1 GB data you will pay 7.5 (1) + 45, similarly, when you need 2 GB data you will pay 7.5 (2) + 45, for 3 GB you will also pay 7.5 (3) + 45. For n GB you will pay 7.5 (n) + 45 hence the equation representing your data expenditure will be y=7.5x+45 where y is the total expenditure.
