Reasoning and answer: Marissa used a total of 4.5 - 1 = 3.5 feet of ribbon to the boxes. Thus, there were 3.5 / 0.7 = 5 boxes.
The answer: 5

Question: Marissa has 4.5 feet of ribbon that she wants to use to tie some boxes. If 1 foot of ribbon is left after Marissa uses 0.7 feet of ribbon to tie each box, find out how many boxes she tied?
Since Greta's brother received 40 letters, Greta received 40 + 10 = 50 letters. Together, Greta and her brother received 50 + 40 = 90 letters. Greta's mother received twice the total number of letters Greta and her brother received, which totals 90 * 2 = 180 letters. In total, the three received 90 + 180 = 270 letters.
The answer: 270
Reverse engineering the question: Greta received 10 more letters in the mail than her brother. Greta's mother received twice the total number of letters Greta and her brother received. Calculate the total number of letters the three received if Greta's brother received 40 letters.
Reasoning and answer: Mark buys 6 $2 cans of soup, meaning he spends 6 * 2 = 12 dollars on soup. Mark buys 2 $5 loaves of bread, meaning he spends 2 * 5 = 10 dollars on bread. Mark buys 2 $3 boxes of cereal, meaning he spends 2 * 3 = 6 dollars on cereal. Mark buys 2 $4 gallons of milk, meaning he spends 2 * 4 = 8 dollars on milk. All added together, this means Mark spends 12 + 10 + 6 + 8 = 36 dollars. Since Mark only has $10 bills, he spends 36 / 10 = 3.6 tens on it, which rounds up to 4 as you cannot spend .6 of an undividable item.
The answer: 4

Question: Mark goes into the store to buy some groceries. He buys 6 2$ cans of soup, 2 $5 loaves of bread, 2 3$ boxes of cereal, and 2 $4 gallons of milk.

Brooke has 2 * 1,000 = 2,000 dollars. Brittany has 4 * 2,000 = 8,000 dollars. Alison has 8,000 / 2 = 4,000 dollars.
The answer: 4000
Reverse engineering the question: Alison has half as much money as Brittany. Brittany has 4 times as much money as Brooke. Brooke has twice as much money as Kent. If Kent has $1,000, how much money does Alison have?
Reasoning and answer: First find the area of the first wall: 5 feet * 8 feet = 40 square feet. Then find the area of the second wall: 7 feet * 8 feet = 56 square feet. Then add the areas of the two walls to find the total area: 40 square feet + 56 square feet = 96 square feet. Then divide the number of square feet by the number of tiles per square foot to find the total number of tiles needed: 96 square feet * 4 tiles / square foot = 384 tiles. Then find the difference in cost per tile: $13 / tile - $11 / tile = $2 / tile. Then multiply the number of tiles by the cost difference per tile to find the total cost difference: $2 / tile * 384 tiles = $768.
The answer: 768

Question: Janet is considering two options to retile her bathroom. The turquoise tiles cost $13/tile and the purple tiles cost $11/tile. If Janet needs to tile two walls that measure 5 feet by 8 feet and 7 feet by 8 feet, and each square foot of wall takes 4 tiles, how much will Janet save by buying the purple tiles instead of the turquoise ones?
Reasoning and answer: Mike is using 40 blocks / 2 = 20 blocks of type B. He uses in total 40 blocks + 20 blocks = 60 blocks of type A and B. So he is going to use 150 blocks - 60 blocks = 90 blocks of other types.
The answer: 90

Question:
Mike is building a bridge out of LEGO blocks. To be successful he needs at least 40 bricks of type A, and half that many of type B. In total, he needs to use 150 bricks. How many bricks of other types than mentioned is he going to use?
