If an investment decreases 1% the first year, 6% the second year and 9% the third year, what is the "average" percent decrease? (Enter answer as a percent, rounded to 1 decimal place). Remember two things. First, percentages are applied using multiplication, so you cannot just add the 3 numbers together and divide by 3. Also, percent increases and decreases result in "percent of" so the factors in the multiplication are NOT the percent decreases, but the "percents of". You have to start by finding the geometric mean of the "percents of" and then use that to give the "average" percent decrease.
