Question

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? answer attempt 1 out of 2 gigabytes submit answer show example

Explanation:

Step1: Define the cost equation

Let \( x \) be the number of gigabytes. The total cost \( C \) is the flat cost plus the cost per gigabyte times the number of gigabytes, so \( C = 39 + 4x \). We know the total cost must be at most \( 49.40 \), so we set up the inequality \( 39 + 4x \leq 49.40 \).

Step2: Solve for \( x \)

Subtract 39 from both sides: \( 4x \leq 49.40 - 39 \). Calculate \( 49.40 - 39 = 10.40 \), so \( 4x \leq 10.40 \). Then divide both sides by 4: \( x \leq \frac{10.40}{4} \). Calculate \( \frac{10.40}{4} = 2.6 \).

Answer:

2.6
