answer attempt 1 out of 2
equation:
answer: g =

Explanation:

Step1: Set up the equation

The flat cost is $44$ and the cost per gigabyte is $4$. So the total cost is $44 + 4g$. She wants the total cost to be $54.40$. So the equation is $44+4g = 54.40$.

Step2: Solve for $g$

Subtract $44$ from both sides:
$$44+4g-44=54.40 - 44$$
$$4g=10.40$$
Divide both sides by $4$:
$$g=\frac{10.40}{4}$$
$$g = 2.6$$

Answer:

Equation: $44 + 4g=54.40$
