Question

under her cell phone plan, london pays a flat cost of $44 per month and $4 per gigabyte. she wants to keep her bill at $54.40 per month. write and solve an equation which can be used to determine g, the number of gigabytes of data london can use while staying within her budget.

Explanation:

Step1: Set up the equation

The flat - cost is $44$ and the cost per gigabyte is $4$. The total bill is the sum of the flat - cost and the cost for the data used. So the equation is $44 + 4g=54.40$.

Step2: Solve for $g$

Subtract 44 from both sides of the equation:
$4g=54.40 - 44$
$4g = 10.40$
Then divide both sides by 4:
$g=\frac{10.40}{4}$
$g = 2.6$

Answer:

The equation is $44 + 4g=54.40$ and the number of gigabytes $g = 2.6$.
