Answer: 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
