A cell phone plan has a base fee of $50 per month. The monthly cost (C) increases by $10 for every gigabytes (g) of data used. Wtite an equation with two variables that represents the total monthly cost (C) of the plan.

C = 10g + 50

Step-by-step explanation:

Let g represent the number of gigabytes of data used.

Let C represent the total monthly cost of using g gigabytes of data.

The cell phone plan has a base fee of $50 per month. The monthly cost (C) increases by $10 for every gigabytes (g) of data used. This means that the equation representing the cost of using g gigabytes in a month is

C = 10g + 50
