Question: Mark is injured so decides to spend more time reading. He used to read 2 hours a day but increased that by 150%. Before he read 100 pages a day. How many pages does he read a week now?
Answer: His reading speed is 100 / 2 = 50 pages a day. He reads 2 * 1.5 = 3 hours more now than before. So now he reads 2 + 3 = 5 hours per day. That means he reads 5 * 50 = 250 pages per day. So he reads 250 * 7 = 1750 pages a week. The answer is 1750.
