Two eighth-grade classes are selling raffle tickets to raise money. One class is selling tickets for $4.80 each and has already raised $250.
The other class is selling tickets for $4.00 each and has already raised $215.
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?

answer choices :

4t + 250 = 4.80t + 215

250t + 4.80 4t + 215
