Question

1. under her cell phone plan, arianys pays a flat cost of $42 per month and $5 per gigabyte. she wants to keep her bill at $66 per month. how many gigabytes of data can she use while staying within her budget?

Explanation:

Step1: Define the cost equation

Let \( g \) be the number of gigabytes. The total cost \( C \) is the flat cost plus the cost per gigabyte times the number of gigabytes. So, \( C = 42 + 5g \). We know \( C = 66 \), so we set up the equation \( 42 + 5g = 66 \).

Step2: Solve for \( g \)

Subtract 42 from both sides: \( 5g = 66 - 42 \)
\( 5g = 24 \)
Divide both sides by 5: \( g=\frac{24}{5}= 4.8 \)

Answer:

4.8
