Question: Josh gets together with 7 friends. Everyone including him puts 5 dollars into a pot. First place gets 80% of the money. Second and third place split the rest. How much money does third place get?
Answer: Step-by-step reasoning process: 7 + 1 = 8 people threw money into the pot. So the amount of money in the pot is 8 * 5 = $40. First place gets 40 * .8 = $32. So there is 40 - 32 = $8 left in the pot after first place gets his cut. So third place gets 8 / 2 = $4.
So the answer is 4.

Question: John is a door-to-door salesman. He visits 50 houses a day. 20% of them buy something from them. Of those that buy something half buy a $50 set of knives and the other half buy a $150 set of knives. How much does he sell a week when he works 5 days a week?
Answer: Step-by-step reasoning process: There are 50 * .2 = 10 houses buying from him per day. Of those 10 / 2 = 5 buy each type of knife set. So he gets 5 * 50 = $250 per day from the cheap set. He also gets 5 * 150 = $750 from the expensive set. So he makes a total of 250 + 750 = $1000 per day. That means he makes 1000 * 5 = $5000.
So the answer is 5000.

Question: Marla has to spend 20 minutes driving one way to her son's school, then 70 minutes attending parent-teacher night, then the same amount of time driving home. How many minutes does Marla spend on this errand in total?
Answer: Step-by-step reasoning process: First multiply Marla's one - way driving time by 2 to find her total driving time: 20 minutes * 2 = 40 minutes. Then add Marla's driving time to the time spent attending the conference to find the total time: 70 minutes + 40 minutes = 110 minutes.
So the answer is 110.

Question: Hannah brought $30 to the county fair. She spent half of it on rides and another $5 on dessert. How much, in dollars, is left?
