$30.00 - $78.00 = $4.00h
$78.00 + $30.00 = $4.00h
$30.00 + $4.00h = $78.00
$30.00 - $4.00h = $78.00

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 + 3x
15 - 10 = 2.5x + 3x

At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal?
150x + 24 = 180 + 20x
150 + 24x = 180 + 20x
180 - 150 = 24 x + 20x
150 - 24x = 180 - 20x
