Question

under her cell phone plan, makayla pays a flat cost of $47.50 per month and $5 per gigabyte. she wants to keep her bill at $70.50 per month. how many gigabytes of data can she use while staying within her budget?

Explanation:

Step1: Set up the equation

Let \(x\) be the number of gigabytes. The total cost is the flat cost plus the cost per gigabyte. So the equation is \(47.50 + 5x=70.50\).

Step2: Solve for \(x\)

Subtract \(47.50\) from both sides: \(5x = 70.50 - 47.50\).
\(5x=23\).
Divide both sides by \(5\): \(x=\frac{23}{5}\).

Answer:

\(4.6\) gigabytes.
