Answer the following question.
Jeff had 300 pencils and donated 30% of them. Vicki had twice as many pencils as Jeff and donated 3/4 of his pencils. How many pencils are there remaining altogether?
Step-by-step reasoning process: Jeff donated 30 / 100 * 300 = 90 pencils. He remained with 300 - 90 = 210 pencils. Vicki had twice as many pencils as Jeff, meaning he had 2 * 300 = 600 pencils. When Vicki donated 3 / 4 of his pencils, he gave away 3 / 4 * 600 = 450 pencils. Vicki remained with 600 - 450 = 150 pencils. Together, Jeff and Vicki remained with 150 + 210 = 360 pencils.
The answer is 360.

Answer the following question.
Willow’s daughter had a slumber party with 3 of her friends. For breakfast, they wanted pancakes. Willow’s pancake recipe makes 1 serving of 4 pancakes. Each of the girls wanted a serving and a half of pancakes. Willow’s son wanted 3 servings of pancakes. How many single pancakes will Willow make for the girls and her son?
Step-by-step reasoning process: The daughter and her 3 friends each want 1.5 servings of pancakes so that’s 4 * 1.5 = 6 servings of pancakes. Willow’s son wants 3 servings of pancakes and the girls want 6 so that’s 3 + 6 = 9 servings of pancakes. Each serving makes 4 pancakes and Willow needs to make 9 servings for a total of 4 * 9 = 36 pancakes.
The answer is 36.

Answer the following question.
The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left?
Step-by-step reasoning process: For the first 30 minutes, 3 * 2 = 6 cups of water came out. For the next 30 minutes, 3 * 2 = 6 cups of water came out. For the next hour, 6 * 4 = 24 cups of water came out. A total of 6 + 6 + 24 = 36 cups of water came out. Shawn had to dump water which left 36 / 2 = 18 cups of water.
The answer is 18.
