Question

solve equations in context (unwinding) 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 an equation

Let $x$ be the number of gigabytes. The equation based on the cost - structure is $47.50 + 5x=70.50$.

Step2: Isolate the term with $x$

Subtract 47.50 from both sides of the equation: $5x=70.50 - 47.50$.
$5x = 23$.

Step3: Solve for $x$

Divide both sides of the equation by 5: $x=\frac{23}{5}=4.6$.

Answer:

4.6
