Under her cell phone plan, Ximena pays a flat cost of $44.50 per month and $4 per gigabyte. She wants to keep her bill at $50.10 per month. How many gigabytes of data can she use while staying within her budget?
x = number of gigabytes
4x + 44.5 = 50.10 {price per GB times number of GB's plus flat fee equals total cost} 4x = 5.6 {subtracted 44.5 from each side} x = 1.4 {divided each side by 4} She can use 1.4 GB. Ask Algebra House
