[Question]Two years ago, Jared was twice as old as Tom. If Tom will be 30 in five years, how old is Jared now?
[Answer]Tom will be 30 in 5 years so now he is 30 - 5 = 25. 2 years ago Tom was 25 - 2 = 23. At that time, Jared was twice as old as Tom so Jared was 23 * 2 = 46. Two years have since passed so Jared is now 46 + 2 = 48. The answer is 48.
Q: Barbie and Bruno have a pile of 144 coconuts that they need to move from one side of their yard to the other side.

If they make trips together carrying their maximum number of coconuts each time, how many trips together would they need to make to move all of the coconuts?
A: Together, they would carry a combined total of 4 + 8 = 12 coconuts per trip. To move 144 coconuts, they would need to make 144 / 12 = 12 trips. The answer is 12.
Question: A family had 10 eggs, but the mother used 5 of them to make an omelet. Then, 2 chickens laid 3 eggs each. How many eggs does the family have now?
Answer: There were 10 eggs but 5 of them were used so, there are 10 - 5 = 5 eggs. Then the two chickens laid 2 * 3 = 6 eggs in total. Thus, the family has 5 + 6 = 11 eggs now. The answer is 11.
Q: Tom needs to buy a new gaming system. He trades in his super Nintendo for an original NES. The SNES is worth $150 and the store gives him 80% of that value. He gives $80 and gets back $10 change and a game worth $30. How much was the NES on sale for?
A:
He traded in the SNES for 150 * .8 = $120. Including the money he gave, he spent 120 + 80 = $200. He got 10 + 30 = $40 in change. So the NES cost 200 - 40 = $160. The answer is 160.
