Answer the following question.
Jo-Bob hopped into the hot air balloon, released the anchor rope, and pulled on the lift chain, which ignited the flame and provided the warm air that caused the balloon to rise. When the lift chain was pulled, the balloon would rise at a rate of 50 feet per minute. But when the chain was not being pulled, the balloon would slowly descend at a rate of 10 feet per minute. During his balloon ride, he pulled the chain for 15 minutes, then released the rope for 10 minutes, then pulled the chain for another 15 minutes, and finally released the chain and allowed the balloon to slowly descend back to the earth. During his balloon ride, what was the highest elevation reached by the balloon?
Step-by-step reasoning process: The first 15 - minute chain pull caused the balloon to rise 50 * 15 = 750 feet. Releasing the chain for 10 minutes caused the balloon to descend 10 * 10 = 100 feet. The second 15 - minute chain pull caused the balloon to rise another 50 * 15 = 750 feet. Thus, at the end of the second chain pull, when the balloon was at its highest elevation, the balloon had risen to an elevation of 750 - 100 + 750 = 1400 feet above the earth's surface.
The answer is 1400.

Answer the following question.
Ginger ended up working 8 hours outside in her garden. She kept a water bottle with her that held 2 cups of water. She drank a full bottle of every hour she was outside. She also poured an additional 5 bottles of water over the new plants she planted. How many cups of water did Ginger drink/use that day?
Step-by-step reasoning process: She drank 2 cups of water every hour for 8 hours so 2 * 8 = 16 cups. She poured 5 bottles of waters on her plants and each holds 2 cups so 5 * 2 = 10 cups of water. She drank 16 cups of water and used 10 cups of water so she had 16 + 10 = 26 cups of water.
The answer is 26.

Answer the following question.
Matt has 8 baseball cards worth $6 each. If he trades two of them to Jane in exchange for 3 $2 cards and 1 $9 card, how much profit does he make?
Step-by-step reasoning process: First find the value of the 2 cards Matt trades: $6 / card * 2 cards = $12. Then find the total value of the 3 $2 cards: 3 cards * $2 / card = $6. Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $3.
The answer is 3.

Answer the following question.
Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo?
Step-by-step reasoning process: In the bottom half of the igloo, there are 10 rows / 2 = 5 rows of bricks of snow. So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = 60 bricks of snow. In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = 40 bricks of snow. There is therefore a total of 60 + 40 = 100 bricks of snow in the igloo.
The answer is 100.
