In western Europe, x bicycles were sold in each of the years 1990 and 1993…

Solution:

We are given that in 1990 the bicycle producers in Western Europe produced and sold 42 percent of the bicycles in that market, and in 1993 they produced and sold 33 percent of the bicycles in that market.

Thus, they produced 0.42(x) bicycles in 1990, and 0.33(x) bicycles in 1993.

The decrease in bicycles produced and sold in Western Europe from 1990 to 1993 was:

0.42(x) – 0.33(x) = 0.09x or 9 percent of x.

Answer: D
