You are thinking about switching cell phone carriers because you don't get very good cell coverage at your new apartment. Verizo
n is offering a new deal on monthly data packages for smartphone. After paying a $45 access fee, each GB of data is $7.50. Write a recursive formula for the monthly cost of a smartphone data package at verizon.
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.
