While planning to finish reading a 140-page book in one week, Jessy initially decides to read 3 times daily, 6 pages each time, every day of the week. How many more pages should she read per day to actually achieve her goal?
To achieve her goal, she must read 140/7 = <T>divide(140, 7)=20.0 pages per day
She planned to read 3 * 6 = <T>multiply(3, 6)=18 pages daily
She must read 20 - 18 = <T>subtract(20, 18)=2 more pages per day
