Some other examples of percent changes: An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. An increase of 800% means the final amount is 9 times the original (100% + 800% = 900% = 9 times as large). A decrease of 60% means the final amount is 40% of the original (100% – 60% = 40%). A decrease of 100% means the final amount is zero (100% – 100% = 0%).
