Calculate Data Usage for Mr. Davis' Family Cell Phone Plan

Understanding Data Usage Calculation

Mr. Davis pays $35 per month for his family's cell phone plan plus $0.50 for each gigabyte of data used. If his bill was $52, we need to determine how many gigabytes of data the family used.

Final Answer:

To find the number of gigabytes of data used, subtract the fixed monthly cost from the total bill and divide by the cost per gigabyte. The family used 34 gigabytes of data.

Explanation:

To find the number of gigabytes of data used, we need to subtract the fixed monthly cost from the total bill and then divide the result by the cost per gigabyte. Let's solve the equation:

Total bill - Fixed monthly cost = Cost per gigabyte * Number of gigabytes

Substituting the given values, we have:
$52 - $35 = $0.50 * Number of gigabytes

Simplifying, we get:
$17 = $0.50 * Number of gigabytes

Dividing both sides by $0.50, we get:
Number of gigabytes = 34

Therefore, the family used 34 gigabytes of data.

Question:

How did we calculate the number of gigabytes of data used by Mr. Davis' family?

Answer:

We calculated the number of gigabytes by subtracting the fixed monthly cost from the total bill and dividing the remaining amount by the cost per gigabyte.
