Question: Emma has saved $230 in her bank account. She withdrew $60 to buy a new pair of shoes. The next week, she deposited twice as much money as she withdrew. How much is in her bank account now?
Answer: Emma had $230 - $60 = $170 left in her bank account after she withdrew $60. The next week, she deposited $60 x 2 = $120. Hence, she now has a total of $170 + $120 = $290 in her bank account. The answer is 290.
[Question]Tomorrow, Pete must finish paying off the last $90 he owes on a bike. He goes through his wallet and finds two $20 bills. Checking his pockets, he finds four $10 bills. Unhappy that he doesn't have the entire amount, he suddenly remembers that he has plastic bottles that can be returned to his local store for cash. If the store pays 50 cents for each bottle, how many bottles will Pete have to return to the store?
[Answer]Pete’s wallet contains 2 * 20 = 40 dollars. The money in Pete’s pockets is 4 * 10 = 40 dollars. In total Pete has 40 + 40 = 80 dollars. He owes 90 dollars on the bike and therefore needs 90 - 80 = 10 more dollars. Since 50 cents is ½ dollar, then the number of bottles required to get 10 dollars is 10 / (1 / 2) = 10 * 2 = 20 bottles. The answer is 20.
Q: Lois has 40 books. She gives a fourth of her books to her nephew. From her remaining books, she donates a third of her books to the library. Then she purchases 3 new books from the book store. How many books does Lois have now?
A: Lois gives 40 / 4 = 10 books to her nephew. Then Lois has 40 - 10 = 30 books. Lois donates 30 / 3 = 10 books to the library. Then Lois has 30 - 10 = 20 books. After purchasing new books, Lois has 20 + 3 = 23 books. The answer is 23.
Question: Two hedgehogs found three baskets, each with 900 strawberries. The hedgehogs then each ate an equal number of strawberries. If 2/9 of the strawberries were remaining out of all the strawberries that were there, calculate the total number of strawberries that each hedgehog ate.
Answer: The total number of strawberries in the three baskets is 3 * 900 = 2700. If 2 / 9 of the strawberries were remaining out of all the strawberries after the hedgehogs ate some, there were 2 / 9 * 2700 = 600 strawberries remaining. The total number of strawberries that the two hedgehogs ate is 2700 - 600 = 2100 strawberries. If the hedgehogs ate an equal number of strawberries, each ate 2100 / 2 = 1050 strawberries. The answer is 1050.
