at the end of 1999 you bought shares in a company for 100 euro. During 2000 the shares increase in value by 10%. During the 2001 the shares decreased in value by 10%. how much were the shares at the end of 2001?

To calculate the value of the shares at the end of 2001, we need to follow these steps:

1. Determine the value of the shares at the end of 2000 after they increased by 10%:
Multiply the initial investment of 100 euros by 1.10 (100 x 1.10 = 110 euros).

2. Determine the value of the shares at the end of 2001 after they decreased by 10%:
Multiply the value of the shares at the end of 2000 by 0.90 (110 x 0.90 = 99 euros).

Therefore, at the end of 2001, the shares would be worth 99 euros.

2000 * 1.1 = 2,200

2,200 * 0.9 = 1,980
