Under his cell phone plan, Gabriel pays a flat cost of $52.50 per month and $5 per gigabyte. He wants to keep his bill under $75 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Gabriel can use while staying within his budget.

1 answer

Let gg represent the number of gigabytes Gabriel can use while staying within his budget.

The flat cost Gabriel pays per month is $52.50, and he also pays an additional $5 per gigabyte. Therefore, the total cost per month can be represented by the equation:

Total cost = $52.50 + $5(gg)

Gabriel wants to keep his bill under $75 per month, so we can set up the inequality:

Total cost ≤ $75

$52.50 + $5(gg) ≤ $75

To solve this inequality for gg, we will first subtract $52.50 from both sides:

$5(gg) ≤ $75 - $52.50

$5(gg) ≤ $22.50

Next, we divide both sides by $5:

gg ≤ $22.50 / $5

gg ≤ 4.5

Therefore, Gabriel can use a maximum of 4.5 gigabytes while staying within his budget. Since gigabytes cannot be fractional, we can conclude that Gabriel can use a maximum of 4 gigabytes while staying within his budget.
