C = 0.175x + 5

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

A phone company has a monthly cellular data plan where a customer pays a flat monthly fee $5 and then a certain amount of money per megabyte (MB) of data used on the phone

Given:

Customer uses 80 MB The monthly cost will be $19.00 (flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone)

So let:

- C is the cost of the data plan

- x is amount of money per megabyte (MB)

We can form the standard equation:

C = mx + b C = mx + 5

In this situation, we have:

19 = m*80 + 5

m = 0.175

So the a linear equation is: C = 0.175x + 5

Hope it will find you well
