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 $3.00 each 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 is the same for both classes?

• 3t + 350 = 2.50t + 225 
• 350t + 2.50 = 225t + 3
• 2.50t + 350 = 3t +225
