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

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

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
