Under his cell phone plan, Angel pays a flat cost of $35 per month and $5 per gigabyte. He wants to keep his bill under $50 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Angel can use while staying within his budget.

Answer 1

The inequality that can be used to determine the number of gigabytes Angel can use while staying within his budget is:

$35 + $5x ≤ $50

Where x represents the number of gigabytes Angel can use.

Now, we can solve the inequality:

$35 + $5x ≤ $50
$5x ≤ $50 - $35
$5x ≤ $15
x ≤ $15 / $5
x ≤ 3

Therefore, Angel can use 3 gigabytes or less while staying within his budget of $50 per month.
