Question: Kennedy’s car can drive 19 miles per gallon of gas. She was able to drive 15 miles to school, 6 miles to the softball park, 2 miles to a burger restaurant, 4 miles to her friend’s house, and 11 miles home before she ran out of gas. How many gallons of gas did she start with?
Answer: Step-by-step reasoning process: Kennedy drove 15 + 6 + 2 + 4 + 11 = 38 miles. She gets 19 miles per gallon of gas, so she started with 38 / 19 = 2 gallons of gas.
So the answer is 2.

Question: Will's mom gave him $74 to go shopping. He bought a sweater for $9, a T-shirt for $11 and a pair of shoes for $30. He then returned his shoes for a 90% refund. How much money does Will have left?
Answer: Step-by-step reasoning process: Will paid $30 for his shoes but then returned them and got 90% of the money back, so he lost 10% of the money, which means 10 / 100 * $30 = $3 is gone. Will spent $9 + $11 + $3 = $23. Will started with $74 - $23 that he spent = $51 remaining.
So the answer is 51.

Question: There are 141 gold balloons and twice as many silver balloons. If the gold and silver balloons were added to 150 black balloons, how many balloons are there in total?
Answer: Step-by-step reasoning process: Gold = 141. Silver = 141 * 2 = 282. 141 + 282 + 150 = 573. There are 573 gold, silver, and black balloons in total.
So the answer is 573.

Question: John releases 3 videos on his channel a day. Two of them are short 2 minute videos and 1 of them is 6 times as long. Assuming a 7-day week, how many minutes of video does he release per week?
Answer:
Step-by-step reasoning process: He releases 1 video that is 2 * 6 = 12 minutes long. So each day he releases 2 + 2 + 12 = 16 minutes of videos. That means he releases 16 * 7 = 112 minutes of videos.
So the answer is 112.
