Q: Cindy and Olaf made 15 candied apples which they will be selling for $2 each, and 12 candied grapes which they will be selling for $1.5. How much will they earn if they sell everything?
A: 48
Step-by-step reasoning process: They will earn 15 x $2 = $30 for the candied apples. They will earn 12 x $1.5 = $18 for the candied grapes. Therefore, Cindy and Olaf will earn $30 + $18 = $48 if they sell everything.


Q: Polly and Gerald went for a fun afternoon riding mini race cars at the munchkin track, which is a one-quarter mile circular track. Polly managed to circle the track 12 times in one half hour, but Gerald's car was malfunctioning, and he only moved at an average speed half of what Polly did. What speed did Gerald's car average, in miles per hour?
A: 3
Step-by-step reasoning process: Polly circled the one - quarter mile track 12 times in 0.5 hours at a speed of 12 / 0.5 = 24 circuits of the track per hour. 24 / 4 = 6 miles per hour. Gerald traveled at a speed half of what Polly traveled for an average speed of 6 / 2 = 3 miles per hour.


Q: To celebrate a recent promotion, Arthur decided to treat himself to dinner at a nice restaurant. He ordered a nice appetizer for $8, a delicious ribeye steak for his entrée at $20, had two glasses of nice red wine with dinner for $3 each, and a slice of caramel cheesecake for dessert for $6. He used a voucher for half off the price of his entrée, but he very thoughtfully tipped his waitress a full 20% of what the full cost of his meal would have been without the discount. How much, including the tip, did Arthur spend on dinner?
A: 38
Step-by-step reasoning process: The cost of his food, before the voucher, was $8 + $20 + $3 + $3 + $6 = $40. The tip was $40 * .20 = $8. The voucher saved him $20 / 2 = $10. So the full price of Arthur's meal, with tip, was $40 - $10 + 8 = $38.


Q: Matt buys a massager. At the lowest setting, it vibrates at 1600 vibrations per second. At the highest setting, it vibrates 60% faster. Matt uses it for 5 minutes at the highest setting. How many vibrations does he experience?
A: 768000
Step-by-step reasoning process: At the highest setting, it vibrates 1600 * .6 = 960 vibrations per second faster than the lowest setting. So it vibrates at 1600 + 960 = 2560 vibrations per second. Matt uses it for 5 minutes so that is 5 * 60 = 300 seconds. That means he experienced 2560 * 300 = 768,000 vibrations.
