Aurora has a cell phone plan that charges $65 for phone service plus $12 for each gigabyte of data used each month. If her bill for September is $113, how many gigabytes of data did she use in September?

She used 4 gigabytes of data in September.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Phone service plan: $65 Cost per gigabyte: $12 Bill: $113

So, to find the number of gigabytes that she used we have to write an equation:

65 + 12x = 113

Where:

x = number of gigabytes

Solving for x

12x = 113-65

12x = 48

x = 48/12

x = 4

She used 4 gigabytes of data in September.

The answer is 4 gigabytes of data were used

If you take 65 and add 12 to it 4 times you get 113 so the answer is 4.
