The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value?

15x + 2.5 = 10x + 3

15 + 2.5x = 10 + 3x

15 - 2.5x = 10

15 - 10 = 2.5x + 3x
