Q: Ed and Jacob already had 2 shells in their shell collection. Then they went to the beach to collect even more. Ed found 7 limpet shells, 2 oyster shells, and 4 conch shells. Jacob found 2 more shells than Ed did. How many shells do the pair have altogether?
A: Ed found 7 shells + 2 shells + 4 shells = 13 shells at the beach. Jacob found 13 shells + 2 shells = 15 shells at the beach. In total Ed and Jacob have 2 shells + 13 shells + 15 shells = 30 shells. The answer is 30.
Question: Colbert is building a treehouse out of wooden planks. The treehouse needs 200 wooden planks. A quarter of these planks come from Colbert’s storage, half of these planks come from Colbert’s parents, 20 planks come from Colbert’s friends and he buys the rest from the store. How many planks of wood does he need to buy from the store to finish his treehouse?
Answer: In Colbert’s storage, there are 200 wooden planks / 4 = 50 wooden planks. From his parents, there are 200 wooden planks / 2 = 100 wooden planks. So in total, Colbert has not had to buy 50 wooden planks from storage + 100 wooden planks from his parents + 20 wooden planks from his friends = 170 wooden planks. He therefore still needs to buy 200 needed wooden planks – 170 owned wooden planks = 30 wooden planks. The answer is 30.
[Question]Jose is a collector of fine wines. His private cellar currently holds 2400 bottles of imported wine and half as many bottles of domestic wine as imported wine. If Jose holds a party and the guests drink one-third of all his wine, how many bottles will remain in his cellar?
[Answer]Jose has half as many bottles of domestic wine as imported wine, or 2400 / 2 = 1200 bottles of domestic wine. In total, he has 2400 + 1200 = 3600 bottles of wine. If the guests drink one - third of all his wine, then they will have consumed 3600 / 3 = 1200 bottles of wine. Thus, after the party, Jose's private cellar will have 3600 - 1200 = 2400 remaining bottles of wine. The answer is 2400.
Q: Carrie is wrapping three birthday presents. One present needs two square feet of wrapping paper to cover. The second present needs three-quarters of that amount. The third present needs the same amount as both other presents put together. How many square feet of wrapping paper does Carrie need for all three presents?
A: The second present needs 3 / 4 * 2 = 1 1 / 2 square feet of wrapping paper. The third present needs 2 + 1 1 / 2 = 3 1 / 2 square feet of wrapping paper. Therefore, Carrie needs 2 + 1 1 / 2 + 3 1 / 2 = 7 square feet of wrapping paper for all three presents. The answer is 7.
Question: Each turtle lays a clutch of 20 eggs. If 40% of the eggs successfully hatch, how many hatchlings do 6 turtles produce?
Answer: First find the number of eggs that each turtle successfully hatches: 20 eggs * 40% = 8 eggs. Then multiply the number of eggs per turtle by the number of turtles to find the total number of eggs: 8 eggs / turtle * 6 turtles = 48 turtles. The answer is 48.
Q: After eating half of the number of fruits he had, Martin remained with twice as many oranges as limes. If he has 50 oranges now, how many fruits did he initially have?
A:
Since the number of oranges that Martin has now is twice the number of limes, there are 50 / 2 = 25 limes. The number of fruits she has now is 50 oranges + 25 limes = 75. If she had eaten half of the number of fruits that she had, initially Martin had 2 * 75 = 150 fruits. The answer is 150.
