Q: At the aquarium, there are twice as many sharks as stingrays. If there are 28 stingrays, how many fish are there?
A: If sharks are twice the number of stingrays, then the number of sharks at the aquarium is 2 sharks / stingray * 28 stingrays = 56 sharks. The number of fish in the tank is 56 sharks + 28 stingrays = 84 fish. The answer is 84.

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: 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. The answer is 35.
