- In order to increase a quantity by 10%, you multiply it by 1.1.
- In order to decrease a quantity by 10%, you multiply it by 0.9.
Starting out with a quantity of 100, we want to increase it 10%, and then decrease THE RESULT by 10%.
(100) x (1.1) = 110
(110) x (0.9) = 99
The ending quantity is 99.
The hypothesis of the question is exactly backwards. The net result is a 1-percent DECREASE.
