For this case we have the following expression:

[tex]y = A (b) ^ x[/tex]

Where,

  • A: initial value
  • b: rate of change
  • x: number of years
  • y: future value

Therefore, replacing values we have:

[tex]y = 12050 * (0.88) ^ 9\\y = 3813.56[/tex]

Answer:

The boat will be worth after 9 years about:

B $ 3,813.56
