Question: A crate can hold 20 kilograms of tomatoes. Tommy has 3 crates which he bought for $330. He wants to sell the tomatoes for $6 per 1 kilogram but 3 kilograms of tomatoes were rotten. How much will be Tommy's profit from selling those tomatoes?
Answer with step-by-step thinking: Tommy has a total of 20 x 3 = 60 kilograms of tomatoes. Only 60 - 3 = 57 kilograms can be sold. His earnings for the tomatoes will be $342. Thus, his profit will be $342 - $330 = $12.
So the answer is 12.

Question: Gary counted the number of whiskers on the faces of his two cats. Princess Puff has 14 whiskers, while Catman Do has 6 less than twice the number of whiskers as Princess puff. How many whiskers does Catman Do have?
Answer with step-by-step thinking:
Twice the number of whiskers as Catman Do is 14 * 2 = 28 whiskers. Catman Do has 6 less than twice the number of whiskers as Princess puff, for a total of 28 - 6 = 22 whiskers.
So the answer is 22.
