Question

under his cell phone plan, suav pays a flat cost of $39 per month and $4 per gigabyte. he wants to keep his bill at $45.40 per month. write and solve an equation which can be used to determine x, the number of gigabytes of data suav can use while staying within his budget. answer attempt 1 out of 3 equation: answer: x =

Explanation:

Step1: Set up the equation

The flat - cost is $39 and the cost per gigabyte is $4. The total cost is the sum of the flat - cost and the cost for $x$ gigabytes. So the equation is $39 + 4x=45.40$.

Step2: Solve for $x$

First, subtract 39 from both sides of the equation:
$4x=45.40 - 39$
$4x = 6.40$
Then, divide both sides by 4:
$x=\frac{6.40}{4}$
$x = 1.6$

Answer:

Equation: $39 + 4x=45.40$
