Answer this question:Amber buys 7 guppies for her pond. Several days later, she sees 3 dozen baby guppies swimming around. Two days after that, she sees 9 more baby guppies. How many guppies does she have now?
3 dozen baby guppies make 3 x 12 = 36 baby guppies. There are a total of 36 + 9 = 45 baby guppies. Adding the adult guppies, there are 7 + 45 = 52 guppies.
The answer is 52.

Answer this question:Liezl prepared four sets of 2-dozen paper cups for her daughter's birthday party. If 5 cups were damaged and 30 were not used, how many paper cups were used?
Since 1 dozen is equal to 12 then 2 dozens of cups is equal to 2 x 12 = 24 cups. So, Liezl prepared a total of 24 cups x 4 sets = 96 paper cups. A total of 5 + 30 = 35 paper cups were not used. Hence, 96 - 35 = 61 paper cups were used.
The answer is 61.

Answer this question:Mark deposited $88 in a bank. Bryan deposited $40 less than five times as much as Mark. How much did Mark deposit in the bank?
Five times the amount Mark deposited is $88 x 5 = $440. So, Mark deposited $440 - $40 = $400.
The answer is 400.

Answer this question:Hallie borrows a book from the library. She reads the entire book in four days. She read 63 pages the first day. On the second day, she read twice the number of pages that she'd read on day one. On the third day, she read 10 mores pages than she read on day two. If the book is 354 pages long, how many pages did she read on the fourth day?
On day two, she read 63 * 2 = 126 pages. On day three, she read 126 + 10 = 136 pages. On day four, she read 354 - 63 - 126 - 136 = 29 pages to finish the book.
The answer is 29.
