...43% for the year? If sales continue to decrease by 43% in each succeeding year, how long will it take for sales to decrease to zero?

A) 1 yr.
B) 2 yrs.
C) 3 yrs.
D) 4 yrs.
E) more than 5 yrs.

How would the work be done?

If you allow sales to be less than one, then it never reaches zero. Otherwise, multiply .43 by itself repeatedly and you can get your answer.
