Question

under his cell phone plan, carlos pays a flat cost of $57 per month and $5 per gigabyte. he wants to keep his bill under $65 per month. write and solve an inequality which can be used to determine x, the number of gigabytes carlos can use while staying within his budget. answer inequality:

Explanation:

Step1: Define total cost inequality

$57 + 5x < 65$

Step2: Subtract flat cost from both sides

$5x < 65 - 57$
$5x < 8$

Step3: Solve for x by dividing by 5

$x < \frac{8}{5}$
$x < 1.6$

Answer:

Inequality: $57 + 5x < 65$
$x < 1.6$
