Reasoning and answer: In the first hour, it produces 60 / 6 = 10 pots. In the last hour, it produces 60 / 5 = 12 pots. 12 - 10 = 2 more pots are produced in the last hour.
The answer: 2

Question: When the machine is cold, as it is in the first hour of production, it takes 6 minutes to produce each molded flower pot. Thereafter, once it is warm, it takes only 5 minutes to produce each pot. How many additional pots are produced in the last hour of the day, compared to the first?
He needs to earn $150 more dollars because 500 - 200 - 150 = 150. He needs to sell 20 games because 150 / 7.5 = 20.

Reasoning and answer: 40 people were roller skating and they all had 2 feet which means there were 40 * 2 = 80 feet. Each foot needs a roller skate and each roller skate has 4 wheels so 80 * 4 = 320 wheels when everyone skated.
The answer: 320

First find the total number of twigs on the tree: 30 branches * 90 twigs / branch = 2700 twigs. Then multiply that number by 30% to find how many twigs have 4 leaves: 2700 twigs * 30% = 810 twigs. Then subtract that number from the total number of twigs to find how many have 5 leaves: 2700 twigs - 810 twigs = 1890 twigs. Then multiply that number by 5 to find the number of leaves on the 5 - leaved twigs: 1890 twigs * 5 leaves / twig = 9450 leaves. Then multiply the number of 4 - leaved twigs by 4 to find the total number of leaves they have: 810 twigs * 4 leaves / twig = 3240 leaves. Then add the two groups of leaves to find the total number of leaves: 9450 leaves + 3240 leaves = 12690 leaves.
The answer: 12690
Reverse engineering the question: James has a small tree outside his window with 30 branches with 90 twigs per branch. 30% of the twigs sprout 4 leaves and the rest sprout 5 leaves. How many leaves are on the tree total?
Reasoning and answer: In the second year, the tree will grow 2 x 1.5 = 3 feet. In the third year, it will grow 3 x 1.5 = 4.5 feet. In the fourth year, it will grow 4.5 x 2 = 9 feet. In the fifth year, it will grow 9 / 2 = 4.5 feet. When the tree is 5 years old, including the first year's growth, it will be this tall 2 + 3 + 4.5 + 9 + 4.5 = 23 feet.
The answer: 23

Question: A papaya tree will grow 2 feet in the first year. In the second year, it will grow 50% more than the first year. In the third year, the tree will grow 50% more than in the second year. In the fourth year, it will grow twice as much as the third year. In the fifth year, it will grow half as much as the fourth year. When the tree is 5 years old, how tall is the tree?
Reasoning and answer: Sid has 12 x 2 = 24 sticks. Sam has 24 x 3 = 72 sticks. Thus, they have 24 + 72 + 12 = 108 popsicle sticks.
The answer: 108
