Under his cell phone plan, Gavin pays a flat cost of $62.50 per month and $5 per gigabyte. He wants to keep his bill at $86.50 per month. How many gigabytes of data can he use while staying within his budget?
g = number of gigabytes
5g + 62.5 ≤ 86.5 {price per gb times number of gb's, plus flat fee, needs to be less than or equal to 86.5} 5g ≤ 24 {subtracted 62.5 from each side} g ≤ 4.8 {divided each side by 5} He can use 4.8 gigabytes or under, and stay within his budget. Ask Algebra House
