Respuesta :

After 7 years, the valu of the boat = 9500(1 - 0.15)^7 = 9500(0.85)^7 = $3,045.48

Answer: After 7 years, the value of the sailboat is $3045.49.

Step-by-step explanation:

Since we have given that

Original value of the sailboat = $9500

Depreciation rate = 15%

Number of years = 7

As we know the formula for "Compound Interest "i.e

[tex]A=P(1-\frac{r}{100})^n[/tex]

where,

A denotes Amount

P denotes original value

r denotes rate of depreciation,

n denotes number of years.

So, our equation becomes ,

[tex]A=9500(1-\frac{15}{100})^7\\\\A=9500(1-0.15)^7\\\\A=9500(0.85)^7\\\\A=\$3045.49[/tex]

Hence, after 7 years, the value of the sailboat is $3045.49.
