Come up with a question and reasoning that would justify [8640] as the answer.
The question is: There are 60 ridges on a vinyl record. Jerry has 4 cases, each with 3 shelves that can hold 20 records each. If his shelves are 60% full, how many ridges are there on all his records?
Reasoning: First find the total number of records that can fit on all the shelves: 4 cases * 3 shelves / case * 20 records / shelf = 240 records. Then multiply that number by 60% to find the number of records actually on the shelves: 240 records * 60% = 144 records. Then multiply that number by 60 to find the number of ridges on all the records: 144 records * 60 ridges / record = 8640 ridges.

Come up with a question and reasoning that would justify [60000] as the answer.
The question is: The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area. But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build?
Reasoning: The house cost 320,000 * 1.5 = $480,000. So it is worth 480,000 - 320,000 = $160,000 more than other houses. So the profit is 160,000 - 100,000 = $60,000 more.

Come up with a question and reasoning that would justify [3] as the answer.
The question is: Niko has bought 9 pairs of socks that cost $2 each and plans to resell them. He wants to gain 25% profit from four of the pairs of socks and $0.2 profit each for the other 5 pairs of socks. How much will his total profit be?
Reasoning: Niko will earn $2 x 25 / 100 = $0.5 profit for each of the first four pairs of socks. So, his total profit for the four pairs of socks will be $0.5 x 4 = $2. His total earnings for the 5 pairs of socks is $0.2 x 5 = $1. Therefore, his total profit will be $2 + $1 = $3.
