Question: Fiona and Casey share the hoodies they own. Between the two of them, they own eight hoodies. Casey owns two more than Fiona. How many hoodies does Fiona own?
Answer: Let H be the number of hoodies Fiona owns. Casey owns H + 2 hoodies. Together, they own H + H + 2 = 2H + 2 = 8 hoodies. Thus, 2H = 8 - 2 = 6 hoodies. Therefore, Fiona owns H = 6 / 2 = 3 hoodies. The answer is 3.
[Question]Rohan owns a 20-square meter coconut farm. Each square meter has 2 coconut trees and each tree has 6 coconuts. If the coconuts can be harvested every 3 months and each coconut costs $0.50, how much will he earn after 6 months?
[Answer]Rohan has a total of 20 x 2 = 40 coconut trees. And he has a total of 40 x 6 = 240 coconuts. So, the total coconut he will have after 6 months is 240 x 2 = 480. Therefore, the total amount he will earn is 480 x $0.50 = $240. The answer is 240.
Q: In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
A: Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students. The answer is 800.
Question: Carson needs to mow the lawn and plant some flowers. Carson has to mow 40 lines to cover the whole yard, and it takes him 2 minutes to mow one line. He also needs to plant 8 rows of flowers, each with 7 flowers, and it takes him half a minute to plant each flower. How many minutes will Carson spend gardening?
Answer: First find the total time Carson spends mowing: 40 lines * 2 minutes / line = 80 minutes. Then find the total number of flowers Carson plants: 8 rows * 7 flowers / row = 56 flowers. Then multiply that number by the time taken to plant each flower to find the total time spent planting flowers: .5 minutes / flower * 56 flowers = 28 minutes. Finally, add that time to the time spent mowing to find the total time spent gardening: 28 minutes + 80 minutes = 108 minutes. The answer is 108.
