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?
Solution:
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
Answer: 1750
