The Summerfield Opera House sold 22,200 tickets this year, but it has been experiencing a 6% drop in sales from one year to the next. If this trend continues, then how many tickets will the opera house sell 2 years from now?

If necessary, round your answer to the nearest whole number.

To find the number of tickets the opera house will sell 2 years from now, we need to calculate the number of tickets sold each year assuming a 6% decrease in sales.

First, we calculate the number of tickets sold after 1 year: 22,200 tickets * (1 - 0.06) = 20,892 tickets

Then, we calculate the number of tickets sold after 2 years: 20,892 tickets * (1 - 0.06) = 19,593.12 tickets

Rounding to the nearest whole number, the opera house will sell 19,593 tickets 2 years from now. Answer: \boxed{19,593}.
