Question

he Speedy Data cell phone company has a basic cell phone plan. This plan includes unlimited talk and text but charges a monthly phone charge fee of $28.00 per month plus $7.50 per 1 GB of data that is used for that month. Write a linear equation that models the monthly cost (C) of the cell phone based on the number of data GB, (d) used. C = If your monthly cell phone bill was $36.50, how many GB of data did you use?

A phone company has a monthly cellular data plan where a customer pays a flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone. If a customer uses 96 MB, the monthly cost will be $31.40. If the customer uses 39 MB, the monthly cost will be $22.85. Find a linear equation for the monthly cost of the data plan, C, as a function of x, the number of MB used. C(x) = Use your equation to find the total monthly cost if 260 MB are used.

00:01 Data cell phone plan has includes talk and text, has a monthly phone charge fee of $28 plus $7 .50 for each gigabyte of data used.
00:14 We want to know the linear model that will represent the monthly cost of the cell phone.
00:19 We're going to have, so our linear cost is going to be the $28 plus $7 .50 and we'll put x for the number of gigabytes.
00:29 So if your monthly cell phone bill is $36 .50, how many gigabytes of data did you use? so your cost is $36 .50 and we can now solve for x to find out how many gigabytes were used...
