Answer:

  176.5%

Step-by-step explanation:

The percentage change can be computed from ...

  percent change = ((new value)/(old value) -1) × 100%

  = (58429/21129 -1) × 100%

  = (2.7653 -1) × 100%

  percent change ≈ 176.5%

Additional comment

The average annual increase can be found by taking the root of the ratio, where the root index is the number of years. The percentage increase each year is that root less 1.

  (2.7653^(1/(2019 -1996)) -1 ≈ 4.5% . . . per year for 23 years
