Step-by-step reasoning process: Brenda's mice had 3 * 8 = 24 baby mice. She gave Robbie 24 / 6 = 4 mice. Thus, she sold 3 * 4 = 12 mice to the pet store. She had 24 - 12 - 4 = 8 mice remaining. She sold 8 / 2 = 4 as feeder mice. Thus, Brenda had 8 - 4 = 4 mice left.
The question and answer:
Question and answer: Brenda raises mice, and her adult mice recently had three litters of 8 each. She gave a sixth of the baby mice to her friend Robbie to keep as pets. She sold three times the number of babies she gave Robbie to a pet store. Half of the remaining mice were sold to snake owners as feeder mice. How many baby mice did Brenda have left?
The answer is 4

Step-by-step reasoning process: If Evan had 200 books two years ago, he currently has 200 - 40 = 160 books. In five years, Evan will have 60 more than 160 * 5 = 800 books which is the number he has now. This means Evan will have 800 + 60 = 860 books in five years.
The question and answer:
Question and answer: Evan owns 40 fewer books than the number he had 2 years ago. Evan will have 60 more than five times as many books as he owns now in five years. If Evan had 200 books two years ago, calculate the total number of books he will have in five years.
The answer is 860

Step-by-step reasoning process: Without the first 10 snowflakes, there are 58 - 10 = 48 snowflakes needed. 48 / 4 = 12 5 - minute intervals are needed to get the additional snowflakes. 12 * 5 = 60 minutes passed.
The question and answer:
Question and answer:
There were 10 snowflakes at first. It snowed an additional 4 snowflakes every 5 minutes. How many minutes passed before there were 58 snowflakes?
The answer is 60
