Reasoning and answer: It will be easy to solve the problem by first calculating how much money she makes in a week at her job by multiplying her hourly rate by the number of hours she works in a week: $8 * 35 = $280 in a week. The weekly earnings need to be multiplied by the number of weeks in a month to get how much she made in a month: $280 * 4 = $1120. The bike’s cost must be subtracted from her earnings made in a month to get how much money is left over after purchasing the bike: $1120 - $400 = $720 is left over after purchasing her bike.
The answer: 720

Reverse engineering the question: Carly collected 7 starfish with 5 arms each and one seastar with 14 arms. How many arms do the animals she collected have in total?


Reasoning and answer: Victor needs 2 * 8 = 16 pieces of chicken for Fried Chicken Dinners. He needs 6 * 2 = 12 pieces of chicken for Chicken Pasta. He needs 3 * 3 = 9 pieces of chicken for Barbecue Chicken orders. Thus, he needs 16 + 12 + 9 = 37 pieces of chicken.
The answer: 37

Two boxes of crayons have 24 x 5 / 8 = 15 unused crayons from each box. So, a total of 15 x 2 = 30 unused crayons are in the two boxes. For the other 2 boxes, there are 24 x 2 / 3 = 16 used crayons from each box. Hence, there are 24 - 16 = 8 unused crayons. So, a total of 8 x 2 = 16 unused crayons are in the other two boxes. Therefore, Madeline has a total of 30 + 16 + 24 = 70 unused crayons.
The answer: 70
Reverse engineering the question: Madeline has 5 boxes with 24 crayons in each. She noticed that 5/8 of the crayons in the 2 boxes were not yet used. In the 2 other boxes, only 2/3 of the crayons were used while the last box was not entirely used. How many unused crayons did Madeline have?


Reasoning and answer: When he gave 40 seashells to his friends, Ali had 180 - 40 = 140 seashells. When he gave another 30 seashells to his brothers, he had 140 - 30 = 110 seashells. He also sold half of the seashells, a total of 1 / 2 * 110 = 55 seashells. He was left with 110 - 55 = 55 seashells.
The answer: 55
