For a show, the Dobie band will earn $15 for each ticket sold. Write an equation for their total profit (p) earned related to the number of tickets (t) that they sell.

• 15p = t

• 15t = p

After paying $5.12 for a salad, Carlos has $27.10 left in his wallet. Which equation can be used to find how much money Carlos had before buying a salad?

• x + 5.12 = 27.10

• x + 27.10 = 5.12

• 5.12 - s = 27.10

• s - 5.12 = 27.10

When Korey went to the store he noticed each package of diapers cost $8. Which equation can be used to find out how many packages of diapers he can purchase if he has $40?

• 8 - d = 40

Becky is preparing for her younger sister's birthday party. She splits a jar of lollilops evenly among 6 goody bags. Each bag ends up with 4 lollipops. Which equation can you use to find the number of lollipops n in the jar?

• n/6 = 4

• n - 4 = 6

• 4n = 6

• n + 6 = 4
