Question: Mandy started reading books with only 8 pages when she was 6 years old. By the time she was twice that age, she was reading books 5 times longer, and 8 years later, she was reading books 3 times longer than that. Presently, she reads books that are 4 times the previous length. How many pages do the books she reads now have?
Answer: Step-by-step reasoning process: Twice the age of 6 is 6 x 2 = 12 years old. At 12 years old, Mandy was reading books 5 x 8 = 40 pages long. 8 years later, Mandy was 12 + 8 = 20 years old. At 20 years old, Mandy was reading books 3 x 40 = 120 pages long. Presently, she reads books that are 120 x 4 = 480 pages long.
So the answer is 480.

Question: There are some jelly beans in a jar. Three fourths of the jelly beans are red, and one quarter of the red jelly beans are coconut flavored. If 750 jelly beans are coconut flavored, how many jelly beans are there in the jar?

Question: Carson is sorting seaweed for various uses. 50% of the seaweed is only good for starting fires. 25% of what's left can be eaten by humans, and the rest is fed to livestock. If Carson harvests 400 pounds of seaweed, how many pounds are fed to livestock?
Answer:
Step-by-step reasoning process: First find what percent of the seaweed can be used for something besides starting fires: 400 pounds / 2 = 200 pounds. Then divide that amount by 4 to find the amount that's eaten by humans: 200 pounds / 4 = 50 pounds. Then subtract that amount from the 200 pounds to find how much is eaten by livestock: 200 pounds - 50 pounds = 150 pounds.
So the answer is 150.
