Two eighth-grade classes are selling raffle tickets to raise money.

One class is selling tickets for $2.50 each and has already raised $350.

The other class is selling tickets for $3 and has already raised $225.

Which equation can be used to find t, the number of tickets each class needs to sell so that the total amount raised by each class is the same?

• 3t + 350 = 2.5t + 225

• 350t + 2.5 = 225t + 3

• 2.5t + 350 = 3t + 225

• none of the above

What is the correct equation in 
Slope-Intercept Form?
(y = mx +b)

• y = x + 2

• y = 2x - 1

• y = -x + 2

• y = -2x - 1

Match each model with the correct equation

• 2 + x = 3x + 4

• -2x - 1 = -3 - 4x

• 2x + 1 = 3 + 4x

• 2 - x = -3x + 4

6x - 1 = 11 + 5x
