Question: John's shirt cost 60% more than his pants. His pants cost $50. How much was John's outfit?
Answer with step-by-step thinking: John's pants cost 50 * .6 = $30 more than his pants. So his shirt cost 50 + 30 = $80. So in total he spent 80 + 50 = $130.
So the answer is 130.

Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 8640.

Question: Paul, a biology teacher, assigns 265 points in the first quarter. There are 4 times as many test points as quiz points, and 5 more quiz points than homework points. How many homework points are there in the first quarter?
Answer with step-by-step thinking:
Let x represent the number of homework points. Quiz:x + 5. Test:4(x + 5) = 4x + 20. Total:x + x + 5 + 4x + 20 = 265. 6x + 25 = 265. 6x = 240. x = 40 points.
So the answer is 40.
