Consider the Q and A. Q: 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?
A: 240
What is the step-by-step reasoning process?
Step-by-step reasoning process: 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.

Consider the Q and A. Q: A dog is being treated for fleas. One flea treatment gets rid of half the fleas. After four treatments, the dog has 14 fleas left. How many more fleas did the dog have before the flea treatments than after?
A: 210
What is the step-by-step reasoning process?
Step-by-step reasoning process: After three treatments, the dog had 14 * 2 = 28 fleas. After two treatments, the dog had 28 * 2 = 56 fleas. After one treatment, the dog had 56 * 2 = 112 fleas. Before any treatments, the dog had 112 * 2 = 224 fleas. Thus, the dog had 224 - 14 = 210 more fleas before the treatments than after.

Consider the Q and A. Q: Hannah fills her kids' stockings with 4 candy canes, 2 beanie babies and 1 book. If she has 3 kids, how many stocking stuffers does she buy total?
A: 21
What is the step-by-step reasoning process?
Step-by-step reasoning process: First find the total number of stocking stuffers one kid gets: 4 candy canes + 2 beanie babies + 1 book = 7 stocking stuffers. Then multiply the number of stocking stuffers per kid by the number of kids to find the total number: 7 stocking stuffers / kid * 3 kids = 21 stocking stuffers.

Consider the Q and A. Q: Jack bought 3 books a month at $20 each. He sells them back at the end of the year for $500. How much money did he lose?
A: 220
What is the step-by-step reasoning process?
Step-by-step reasoning process:
He bought 3 * 20 = $60 of books a month. That means he bought 60 * 12 = $720 of books a year. So he lost 720 - 500 = $220.
