Question: 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?
Answer: 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.
So the answer is 4.

Question: Walmart sells a multitool with a screwdriver, 3 knives, and two other tools. Target sells a multitool with a screwdriver, twice as many knives as Walmart, three files and a pair of scissors. How many more tools does the Target multitool have compared to Walmart?
Answer: Step-by-step reasoning process: First find the total number of tools in the Walmart multitool: 1 tool + 3 tools + 2 tools = 6 tools. Then find the total number of knives in the Target multitool: 3 knives * 2 = 6 knives. Then find the total number of tools in the Target multitool: 1 tool + 6 tools + 3 tools + 1 tool = 11 tools. Then subtract the number of tools in the Walmart multitool from the number in the Target multitool to find the difference: 11 tools - 6 tools = 5 tools.
So the answer is 5.

Question: Christopher uses 1 packet of a sugar substitute in his coffee. He has 2 coffees a day. The packets come 30 to a box and cost $4.00 a box. How much will it cost him to have enough sugar substitutes to last him 90 days?
Answer: Step-by-step reasoning process: He uses 1 packet per cup of coffee and he has 2 cups a day so that's 1 * 2 = 2 packets. He wants enough to last him 90 days and he uses 2 packets a day so that's 90 * 2 = 180 packets. The packets come 30 to a box and he needs 180 packets so that's 180 / 30 = 6 boxes of sugar substitute. Each box costs $4.00 and he needs 6 boxes so that's 4 * 6 = $24.00.
So the answer is 24.

Question: Kevin has been for a run and wants to calculate how far he traveled. He ran at 10 miles per hour for half an hour, 20 miles per hour for half an hour, then ran at 8 miles per hour for 15 minutes. How many miles has Kevin run?
Answer:
Step-by-step reasoning process: At his first speed, Kevin ran 10 miles per hour * 0.5 hours = 5 miles. At his second speed, he ran 20 miles per hour * 0.5 hours = 10 miles. 15 minutes is a quarter of an hour so at his third speed, he ran 8 miles per hour * 0.25 hours = 2 miles. Therefore, Kevin ran a total of 5 miles + 10 miles + 2 miles = 17 miles.
So the answer is 17.
