Question: Jackie can do 5 push-ups in 10 seconds. How many push-ups can she do in one minute if she takes two 8-second breaks?
Answer: Step-by-step reasoning process: There are 60 seconds per minute, so Jackie’s push - up routine takes 1 * 60 = 60 seconds. Her breaks last 2 * 8 = 16 seconds. She does push - ups for 60 - 16 = 44 seconds. She can do a push - up in 10 / 5 = 2 seconds. Therefore, Jackie can do 44 / 2 = 22 push - ups in one minute with breaks.
So the answer is 22.

Question: Selena reads a book with 400 pages. Harry reads a book with 20 fewer than half the number of pages Selena's book has. How many pages are in the book of Harry?
Answer: Step-by-step reasoning process: Half the number of pages of Selena is 400 / 2 = 200. Therefore, Harry's book has 200 - 20 = 180 pages.
So the answer is 180.

Question: Mr. Mayer bought Corgi dogs for $1000 each. He plans to sell them with a 30% profit. If one of his friends wants to buy two dogs, how much should his friend pay?
Answer: Step-by-step reasoning process: Mr. Mayer wants to get a $1000 x 30 / 100 = $300 profit. So, he will sell each Corgi dog for $1000 + $300 = $1300. Hence, his friend should pay $1300 x 2 = $2600.
So the answer is 2600.

Question: Kalani has twenty candles in her bedroom, twice the number of candles in the living room. Donovan, her brother, brings in 20 more candles he bought from the candle shop. What's the total number of candles in the house?
Answer:
Step-by-step reasoning process: If the number of candles in the bedroom is twice the number in the living room, there are 20 / 2 = 10 candles in the living room. When Donovan brings in 20 more candles, the total number of candles becomes 10 + 20 + 20 = 50.
So the answer is 50.
