Question

Alina by several shares of stock at $28 per-share and sells them at $24.50 per-share what is the percent of decrease in the price of the stock

Answer 1

Take the absolute value of the difference, then divide it by the original amount
|28 - 24.5| / 28 = 3.5/28 = 0.125..now we multiply that by 100 to get it into a percent 0.125 * 100 = 12.5% <== ur answer

Answer 2

Buy =  $28

Sell = $24.50

Decrease = 28 - 24.50 = 3.5

% Decrease = (3.5 / 28) * 100%

                       = 12.5%
