Frank paid $41 total for 5 books and 1 magazine. The magazine costs $6 and each book cost the same amount. Which equation represents this situation where b is the price of a book. 

• b= (5x41) - 6

• 41= 5 + b + 6

• 41= (5 x b) + 6

• b= (5x6) + 41

Mrs. Rucker made 24 tacos. Her family ate 13 of them. Then Mrs. Rucker made 12 more tacos. Which equation can be used to find t, the number of tacos she had then? 

• 24 + 13 - 12 = t

• 24 + 13 + 12 = t

• 24 - 13 + 12 = t

• 24 - 13 - 12 = t

Ansie bought 2 bags with 10 bows and 3 bags with 14 bows. She used 23 of the bows on graduation gifts she wrapped. Which equation can be used to solve for b, the number of bows Ansie has left?

• (2 x 10) + (3 x 14) - 23 = b

• (2 x 10) + 14 - 23 = b

• 2 x 10 + 3 x (14 + 23) = b

• (2 + 10) x (3 + 14) - 23 = b

The total weight of a computer hard drive, a monitor, and a keyboard is 362 ounces.  The hard drive weighs 318 ounces and the monitor weighs 33 ounces.  Which equation represents the situation where k is the weight of the keyboard?

• 362 = 318 + 33 - k

• 362 = 318 + 33 + k

• 362 = 318 + k

• 362 = 318 - k

Twenty of Erin's friends each agreed to donate $5 to her fundraiser. Which equation can be used to determine d, the amount of money Erin's friends donated to her fundraiser?

• 20 ÷ d = 5

• 20 + 5 = d

• 20 × 5 = d

• 5 × d = 20

At Lincoln Elementary School, the fifth-grade students have a total of 325 pets. Of these pets, 250 are some kind of pet other than cats. Which equation could be used to determine the number of pets that are cats, c?

• 325 + 250 = c

• 325 – 250 = c
  

• 325 × 250 = c

• 325 ÷ 250 = c

Pedro ordered 24 boxes of baseballs.  Each box contained 16 baseballs.  Pedro used 8 of these baseballs during a game.  Which equation can be used to find b, the total number of these baseballs that Pedro did NOT use during the game?

• b = (24 + 16) - 8

• b = (24 x 16) - 8

• b = (24 - 16) / 8

• b = (24 x 16) + 8
