Peter and 2 friends spent 21 on movie tickets and 2 boxes of popcorn at $6 each. If m represents the cost of one ticket, what equation best represents the situation?

• 21 = 3m + 6

• 6 = 21+ 6-m

• 12+3m = 21

• 3m = 21-12

Jon has a $21.61 balance on his gift card. He bought some songs that cost $1.29 per song. Now he has $10 left in his credit card. If d is the number of songs Jon purchased, what equation best represents the situation?

• 21,61 = 1.29+d

• 21.61 - 1.29 d = 10

• 1.29 d = 21.61 - 10

• d = 1.29 + 10 - 21.61
