Although appealing to more refined tastes, art as a collectible has not always performed so profitably. During 2015, an auction house sold a painting for a price of $1,080,000. Unfortunately for the previous owner, he had purchased it three years earlier at a price of $1,660,000. What was his annual rate of return on this painting? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.)

Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding
