To determine Li's salary for her fourth year, we first need to examine the pattern of her salary increases over the first three years.

- From the first year to the second year, her salary increased by: $22,500 - $21,000 = $1,500.
- From the second year to the third year, her salary increased by: $24,000 - $22,500 = $1,500.

The pattern suggests that her salary increases by $1,500 each year.

Therefore, to calculate Li's salary for her fourth year, we add $1,500 to her salary from the third year: $24,000 + $1,500 = $25,500.

Hence, Li will earn $25,500 in her fourth year.

The correct answer is:
$25,500
