Under his cell phone plan, William pays a flat cost of \( \$ 54.50 \) per month and \( \$ 3 \) per gigabyte. He wants to keep his bill at \( \$ 66.20 \) per month. Write and solve an equation which can be used to determine \( g \), the number of gigabytes of data William can use while staying within his budget. \( 70 \% \) Answer Attempt 1 out of 24 Equation: Answer: \( g= \)

To determine how many gigabytes of data \( g \) William can use without exceeding his monthly budget, we can set up the following equation: \[ 54.50 + 3g = 66.20 \] Now, we'll solve for \( g \): 1. Subtract \( 54.50 \) from both sides: \[ 3g = 66.20 - 54.50 \] \[ 3g = 11.70 \] 2. Divide both sides by \( 3 \): \[ g = \frac{11.70}{3} \] \[ g = 3.9 \] Since gigabytes must be a whole number, William can use a maximum of \( 3 \) gigabytes to stay within his budget. So the final answer is \( g = 3 \).
