The arboretum sold 123 tickets on Friday, 312 tickets Saturday, and 276 tickets Sunday. Each ticket was $8. Which of the following equations accurately represents the value of t, the total value of all the tickets sold?

• 123 + 312 + 276 × 8 = t

• t = 8(123 + 312 + 276)

• t = 123 + 312 + 276

• (123 × 8) + (312 × 8) = t

Mrs. Hendrix made 84 cookies. She kept 15 cookies for her family, and divided the remaining cookies equally into 23 goodie bags to give to her students as a gift. How many cookies, c, did each student receive in their goody bag?

• c = 4 because (84 – 15) ÷ 23 = c

• c = 1,587 because (84 – 15) × 23 = c

• c = 3 because (84 – 15) ÷ 23 = c

• c = 69 because 84 – 15 = c

Joseph has 64 stamps in his collection. He put his stamps into an album with 8 stamps on each page. The album has 12 pages. How many stamps, s, can Joseph still fit into the album?

• s = 32 because s = [12 – (64 ÷ 8)] × 8

• s = 64 because s = 8 × (64 ÷ 8)

• s = 160 because s = [(64 ÷ 8) + 12] × 8

• s = 4 because s = 12 – (64 ÷ 8)

Jeremy has a square picture frame with side lengths measuring 15 inches. Which of the following equations best represents p, the perimeter of the frame?

• p = 4 × 15

• p = 2 × 15

• p = 15 × 15

• p = 15 ÷ 4

Jacob wants to drink 128 ounces of water every day. Today he has had 5 bottles of water. Each bottle of water contains 16 ounces of water. How many more bottles of water, b, does Jacob need to drink to reach his goal?

• Jacob needs to drink 3 more bottles of water to reach his goal because (128 ÷ 16) – 5 = b

• Jacob needs to drink 48 more bottles of water to reach his goal because 128 – (16 × 5) = b

• Jacob needs to drink 8 more bottles of water to reach his goal because 128 ÷ 16 = b

• Jacob needs to drink 24 more bottles of water to reach his goal because [128 – (16 × 5)] ÷ 2 = b
