Question: Half of Taylor's house guests like weak coffee and the other half like strong coffee in the morning. Taylor uses 1 tablespoon of coffee per cup of water to make it weak and he doubles that amount to make it strong. If he makes 12 cups of both weak and strong coffee, how many tablespoons of coffee will he need?
Answer with step-by-step thinking: He uses 1 tablespoon for weak coffee and doubles that for strong so the strong uses 1 * 2 = 2 tablespoons. For the weak coffee he uses 1 tablespoon per 1 cup of water and he needs to make 12 cups so he'll use 1 * 12 = 12 tablespoons. For the strong coffee he uses 2 tablespoons per 1 cup of water and he needs to make 12 cups so he'll use 2 * 12 = 24 tablespoons. All total he will use 12 tablespoons for the weak coffee and 24 tablespoons for the strong coffee for a total of 12 + 24 = 36 tablespoons.
So the answer is 36.

Question: Peter carried $500 to the market. He bought 6 kilos of potatoes for $2 per kilo, 9 kilos of tomato for $3 per kilo, 5 kilos of cucumbers for $4 per kilo, and 3 kilos of bananas for $5 per kilo. How much is Peter's remaining money?
Answer with step-by-step thinking: The price of potatoes is 6 * 2 = $12. The price of tomatoes is 9 * 3 = $27. The price of cucumbers is 5 * 4 = $20. The price of bananas is 3 * 5 = $15. The total price Peter spent is 12 + 27 + 20 + 15 = $74. The amount left with Peter is $500 - $74 = $426.
So the answer is 426.

Question: Niko has bought 9 pairs of socks that cost $2 each and plans to resell them. He wants to gain 25% profit from four of the pairs of socks and $0.2 profit each for the other 5 pairs of socks. How much will his total profit be?
Answer with step-by-step thinking:
Niko will earn $2 x 25 / 100 = $0.5 profit for each of the first four pairs of socks. So, his total profit for the four pairs of socks will be $0.5 x 4 = $2. His total earnings for the 5 pairs of socks is $0.2 x 5 = $1. Therefore, his total profit will be $2 + $1 = $3.
So the answer is 3.
