Question: Dan's skateboarding helmet has ten more craters than Daniel's ski helmet. Rin's snorkel helmet has 15 more craters than Dan's and Daniel's helmets combined. If Rin's helmet has 75 craters, how many craters are in Dan's helmet?
Answer: Step-by-step reasoning process: If Rin's snorkel helmet has 75 craters, then Dan's and Daniel's helmets combined have 75 - 15 = 60 craters. Let's assume Dan's helmet has C craters. Since Dan's skateboarding helmet has ten more craters than Daniel's ski helmet, the total number of craters their helmets have is C + (C - 10) = 60. 2C = 60 + 10. The total number of craters that Dan's helmet has is C = 70 / 2. Dan's skateboarding helmet has 35 craters.
So the answer is 35.

Question: A store gives a 10% discount for the amount of the sell that was over $1000. John buys 7 items that each cost $200. What does his order cost after the discount?
Answer: Step-by-step reasoning process: His order came out to 7 * 200 = $1400. So there was 1400 - 1000 = $400 that qualified for the discount. So his discount saved 400 * .1 = $40. So his purchase came out to 1400 - 40 = $1360.
So the answer is 1360.

Question: Albert has to run 99 meters in gym class. The track is 9 meters around. He has already run 6 times around it. Once he finishes, how many more complete laps will he have made around the track?
Answer: Step-by-step reasoning process: Albert has to run 11 laps in total because 99 / 9 = 11. He has 5 more complete laps to run because 11 - 6 = 5.
So the answer is 5.

Question: Sol sells candy bars to raise money for her softball team. On the first day, she sells ten candy bars and sells four more candy bars than she sold the previous day each day afterward. If she sells six days a week and each candy bar costs 10 cents, how much will she earn in a week in dollars?
Answer:
Step-by-step reasoning process: Sol will sell 10 + 4 = 14 candies on the second day. She will sell 14 + 4 = 18 candies on the third day. She will sell 18 + 4 = 22 candies on the fourth day. She will sell 22 + 4 = 26 candies on the fifth day. She will sell 26 + 4 = 30 candies on the sixth day. She will sell a total of 10 + 14 + 18 + 22 + 26 + 30 = 120 candies in a week. Hence, she will earn 120 x 10 = 1200 cents. Since 1 dollar is equal to 100 cents, then Sol will earn 1200 / 100 = $12.
So the answer is 12.
