Question

under her cell phone plan, shaniece pays a flat cost of $48 per month and $3 per gigabyte. she wants to keep her bill at $61.20 per month. which equation could be used to determine $x$, the number of gigabytes of data shaniece can use while staying within her budget? answer 61.2 = 48x + 3 3x + 48 = 61.2 3(x + 48) = 61.2 48x = 61.2 - 3

Explanation:

Step1: Identify fixed and variable costs

The flat - cost is $48 per month and the cost per gigabyte is $3. Let $x$ be the number of gigabytes. The variable cost for data is $3x$.

Step2: Set up the equation

The total bill is the sum of the flat - cost and the variable cost for data. We know the total bill should be $61.20$. So the equation is $3x + 48=61.2$.

Answer:

$3x + 48 = 61.2$
