It took Ian three years to collect 25,413 aluminum cans to recycle. In the first year he collected 8,917 cans, and in the second year he collected 7,639 cans.

Which equation can be used to find x, the number of cans Ian collected in the third year?

• x = 25,413 - 8,917 - 7,639

• x = 25,413 + 8,917 + 7,639

• x = 8,917 + 7,639

• x = 8,917 - 7,639

A toy store ordered three boxes of a new toy. Each box contained 20 toys. When the boxes arrived, four of the toys were broken. Which equation shows how to find n, the

number of toys that were not broken?

• 3 + 20 4 = n

• 3 × 20 ÷ 4 = n

• 3 + 20 ÷ 4 = n

Alex spent $80 at the mall last weekend. He bought 5 shirts and a video game. The video game cost $25. If each shirt, s, cost the same amount of money, which equation determines the cost of each shirt?

• s = (80 - 25) x 5

• s = (80 + 25) ÷ 5

• s = (80 - 25) + 5

• s = (80 - 25) ÷ 5

Dominic made 4 batches of 12 cookies each. He made snack bags of 3 cookies each. Which equation shows how to find n, the number of bags Dominic is able to make?

• (4 x 12) x 5 = n

• (4 + 12) ÷ 5 = n

• (4 x 12) - 3 = n

• (4 x 12) ÷ 3 = n

A ticket to the movies costs $12 for adults and $8 for children. A family of two adults and four children go to the movies. Which equation shows how to find t, the total cost of their entrance fee?

• t = (2 x 8) + (4 x 12)

• t = (2 x 12) + (4 x 8)

• t = (2 + 12) + (4 x 8)

• t = (2 + 12) x (4 +8)
