Two seventh-grade classes are selling raffle tickets to raise money.
-One class is selling tickets for $3.50 each and has already raised $400.
-The other class is selling  tickets for $2.00 each and has already raised $300.
Which equation can be used to find m, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?

• 5.5m = 700
• 3.50m = 2m + 300
• 3.5m + 400 = 2m + 300
• 3.5 + 400m = 2 + 300m
