Question: Mindy has 7 less than 9 times as many emails waiting for her as phone messages. If she has a total of 93 emails and phone messages combined, how many emails does she have?
Answer: Step-by-step reasoning process: Let e be the number of emails Mindy has and m be the number of phone messages? We know that e + m = 93 and e = 9m - 7. Substituting the second equation into the first equation, we get 9m - 7 + m = 93. Combining like terms, we get 10m - 7 = 93. Adding 7 to both sides of the equation, we get 10m = 100. Dividing both sides by 10, we get m = 10. Substituting this value back into the equation e = 9m - 7, we get e = 9 * 10 - 7 = 90 - 7 = 83.
So the answer is 83.

Question: Kayla and Theresa went to buy some chocolate bars and soda cans. Theresa bought twice the number of chocolate bars and soda cans Kayla bought. If Theresa bought 12 chocolate bars and 18 soda cans, how many chocolate bars and soda cans did Kayla buy in total?
Answer: Step-by-step reasoning process: Kayla bought 12 chocolate bars / 2 = 6 chocolate bars. She also bought 18 soda cans / 2 = 9 soda cans. The total number of chocolate bars and soda cans Kayla bought is 6 chocolate bars + 9 soda cans = 15 items.
So the answer is 15.

Question: A large puzzle costs $15. A small puzzle and a large puzzle together cost $23. How much would you pay for 1 large and 3 small puzzles?
Answer: Step-by-step reasoning process: A small puzzle costs $23 - $15 = $8. Three small puzzles cost $8 x 3 = $24. So, 1 large and 3 small puzzles cost $24 + $15 = $39.
So the answer is 39.

Question: Riku has 25 times more stickers than Kristoff. If Kristoff has 85 stickers, how many stickers does Riku have?
