Answer 1

To compare the balance at the end of 2001 to the balance at the beginning of 2000, we need to consider the cumulative increase over the two years.

In 2000, the balance increased by 40%. This means the balance at the beginning of 2001 would be 100% + 40% = 140% of the initial balance.

In 2001, the balance increased by an additional 30%. This means the balance at the end of 2001 would be 140% + 30% = 170% of the initial balance.

Therefore, the balance at the end of 2001 is 170% of the balance at the beginning of 2000.
