.
Home values in a town have declined 27 % per year for each of the past four years.
What was the total percentage decrease in home values during the four-year period?
~~~~~~~~~~~~~~~~~~~~~~~~
The solution in the post by @josgarithmetic, giving the answer " PerCent Decrease, "
is INCORRECT and TOTALLY WRONG.
I came to bring you a correct solution and a correct answer. See below
Home values at the beginning 1
Home values in one year after (1-0.27)
Home values in two years after
Home values in three years after
Home values in four years after = 0.2840, or 28.4% (rounded).
The total percentage decrease in 4 years is 100% - 28.4% = 71.6%, rounded.
Solved (correctly).
