$($Answer is not a $40\%)$

You decide to buy $1,100$ shares of stock at a price of $$82$ and an initial margin of $80$ percent. What is the maximum percentage decline in the stock price before you will receive a margin call if the maintenance margin is $40$ percent?

Note: Do not round intermediate calculations. Enter your answer as a percent rounded to $2$ decimal places. Input the amount as a positive value.
