Q: Aitana and Jayda went to Silverlake Flea market to buy some handmade crafts. Aitana spent 2/5 times more money than Jayda at the market. If Jayda spent $400, calculate the total amount of money they spent together.
A: If Jayda spent $400 at the market, Aitana spent 2 / 5 * 400 = $160 more on handmade crafts. Since Aitana spent $160 more than Jayda at the market, she spent $400 + $160 = $560. The total amount of money they spent together is $400 + $560 = $960. The answer is 960.

Q: Joseph and his friends watched two movies in his house. The first movie is 1 hour and 30 minutes long while the second movie is 30 minutes longer than the first. Before the movies, they spent 10 minutes making popcorn and twice as long making fries. How long, in hours, did it take Joseph and his friends to cook and watch the movies?
A: The first movie was 60 + 30 = 90 minutes long since an hour has 60 minutes. The second movie was 90 + 30 = 120 minutes long. It took them a total of 90 + 120 = 210 minutes to watch the two movies. It took them 10 x 2 = 20 minutes to cook the fries. Thus, it took them a total of 10 + 20 = 30 minutes to cook. So, they spent 210 + 30 = 240 minutes watching the movies and cooking. In hours, this is equal to 240 / 60 = 4 hours. The answer is 4.

Q: A carpenter is building a house. He needs 80 woodblocks to build it. If he has 8 logs that can make five woodblocks each, how many logs does the carpenter still need?
A:
The carpenter initially has 8 x 5 = 40 blocks of wood. So he still lacks 80 - 40 = 40 blocks of wood. Therefore he still needs 40 / 5 = 8 logs of wood. The answer is 8.
