Danny collects stamps and displays them in a stamp book. The book has 6 pages with 12 stamps per page and 9 pages with 10 stamps per page. He sells 15 stamps at a stamp show. Which equation represents s, the number of stamps he has now?

• (6 x 12) + (9 x 10) - 15 = s

• (6 x 12) x (9 x 10) - 15 = s

• (6 + 12) + (9 + 10) - 15 = s

• (6 + 12) x (9 + 10) - 15 = s

Kelsey has 8 sheets of stickers with 12 stickers on each sheet. Ricardo has 10 sheets of stickers with 15 stickers on each sheet. Ricardo buys 4 more sheets of stickers like the ones he has. Which equation could you use to find s, how many more stickers Ricardo has than Kelsey has?

• 10 x 15 + 8 x 12 = s

• 8 x 12 - 10 x 15 = s

• (15 + 4) x 10 + 8 x 12 = s

• (10 + 4) x 15 - 8 x 12 = s
