question
under his cell phone plan, deion pays a flat cost of $39 per month and $4 per gigabyte. he wants to keep his bill at $49.40 per month. how many gigabytes of data can he use while staying within his 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 times the number of gigabytes. So the equation is \(39 + 4x=49.40\).

Step2: Solve for \(x\)

Subtract \(39\) from both sides: \(4x=49.40 - 39\).
\(4x = 10.40\).
Divide both sides by \(4\): \(x=\frac{10.40}{4}\).
\(x = 2.6\).

Answer:

\(2.6\) gigabytes.
