Answer 1

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.

Answer 2

She used 4 gigabytes of data in September.

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.
