Jessie won 3 times as many athletic awards as his buddy Scott, who won 4 awards. The best athlete at the rival high school won twice as many awards as Jessie. How many awards did the rival win? Give the rationale and then the answer.
Let's think step by step. Jessie won 3 times the amount of the 4 awards that Scott won so he won 3 * 4 = 12 awards. The rival athlete won twice the awards as Jessie, who won 12 so he won 2 * 12 = 24 awards.. The answer is: 24.

Jared counted 15% fewer cars than his sister Ann while they were watching the road from the school, and Ann counted 7 more cars than their friend Alfred. If Jared counted 300 cars, how many cars did all of them count? Give the rationale and then the answer.
Let's think step by step. If Jared counted 300 cars, and Ann counted 15% more, then Ann counted 1.15 * 300 = 345 cars. If Ann counted 7 cars more than their friend Alfred, then Alfred counted 345 - 7 = 338 cars. The total number of cars counted by all of them will be 338 + 345 + 300 = 983 cars.. The answer is: 983.

Colby harvested his mango trees, the total mangoes he harvested is 60 kilograms. He sold 20 kilograms to the market and sold the remaining half to his community. If each kilogram contains 8 mangoes, how many mangoes does he still have? Give the rationale and then the answer.
Let's think step by step. He has 60 - 20 = 40 kilograms of mangoes left after selling them to the market. Colby sold 1 / 2 x 40 = 20 kilograms of mangoes to the community. Therefore, Colby still has 20x8 = 160 pieces of mangoes.. The answer is: 160.
