Answer the following question.
Jess made 3 different stacks of wooden blocks. The first stack was 7 blocks high, the second stack was 5 block(s) higher than the first, and the final stack was 7 block(s) higher than the second. Jess' little sister knocked over the entire first tower, in the second tower she left 2 blocks standing, and in the final tower she left 3 blocks standing. How many blocks in total fell down?
Step-by-step reasoning process: Jess' second stack was 7 blocks + 5 blocks = 12 blocks. Jess' third stack was 12 blocks + 7 blocks = 19 blocks high. Jess' sister knocked down the second tower and knocked 12 blocks 2 = 10 blocks knocked over. Jess' sister knocked down the final tower and knocked 19 blocks 3 = 16 blocks knocked over. Total blocks knocked over was 7 blocks + 10 + 16 = 33 blocks.
The answer is 33.

Answer the following question.
Jeremy loves to play Scrabble. He once played a three-letter word on a triple word score to earn thirty points. If before the word score was tripled, the first and third letters were each valued at one point apiece, how much was the middle letter valued at before the word score was tripled?
Step-by-step reasoning process: Since the word score after being tripled was 30 points, then the word score before tripling was 30 / 3 = 10 points. If before the word score was tripled, the first and third letters were each valued at one point apiece, then the value of the middle letter was 10 - 1 - 1 = 8 points.
The answer is 8.

Answer the following question.
Jenna works as a truck driver. She gets paid $0.40 cents per mile. If she drives 400 miles one way, how much does she get paid for a round trip?
Step-by-step reasoning process: First find the total number of miles Jenna drives: 400 miles / way * 2 ways = 800 miles. Then multiply that number by her pay per mile to find her total pay: 800 miles * $0.40 / mile = $320.
The answer is 320.

Answer the following question.
Billy is counting the rings in two trees. Weather fluctuations in this area mean that each tree's rings are in groups of two fat rings and four thin rings. If Billy counts 70 ring groups in the first tree and 40 ring groups in the second tree, how much older is the first tree? (Trees grow 1 ring per year.)
Step-by-step reasoning process: First find the total number of rings in a ring group: 2 rings + 4 rings = 6 rings. Then subtract the number of ring groups in the second tree from the number in the first tree to find the difference: 70 groups - 40 groups = 30 groups. Then multiply that number by the number of rings in a group to find the difference in the trees' ages: 30 groups * 6 rings / group = 180 rings, or 180 years.
The answer is 180.
