Reasoning and answer: Infertile:30(.20) = 6. 30 - 6 = 24 eggs remain. Calcification Issues:24(1 / 3) = 8. 24 - 8 = 16 eggs that will hatch.
The answer: 16

Question: A gecko lays 30 eggs per year. 20 percent of them are infertile, and a third of the remaining eggs will not hatch due to calcification issues. How many eggs actually hatch?
If Luke is 20, he will be 20 + 8 = 28 years old in eight years. In eight years, Mr. Bernard will be 3 times as old as Luke is now, a total of 3 * 20 = 60 years old. Mr. Bernard is now 60 - 8 = 52 years old. The sum of their current ages is 52 + 20 = 72. Their average age is 72 / 2 = 36. 10 less than their average age is 36 - 10 = 26 years.
The answer: 26
Reverse engineering the question: In eight years, Mr. Bernard will be 3 times as old as Luke is now. If Luke is 20, what is 10 years less than their average age?

Rosie will get $1 - $.44 = $.56 in change. She will get 2 quarters to account for $.50 of the change. She will also get 1 nickel to account for $.05 of the change. Then, she will get 1 penny, to account for the last $.01 of the change. She will get 2 + 1 + 1 = 4 coins total.
The answer: 4
Reverse engineering the question: Rosie pays for a $.44 piece of candy with a $1 bill. If the cashier gives her the smallest number of coins possible as change, how many coins will Rosie get as change?
Reasoning and answer: The amount she spends on buying drinks is $2 * 10 = $20. The amount she spends on buying cakes is $10 * 5 = $50. The amount she spends on buying ice creams is $5 * 100 = $500. The total amount she spends is $20 + $50 + $500 = $570.
