Answer:
4.37%
Explanation:
Given: Value of object in 1997 is $5000
Value of object in 2012 is $4500.
Number of years (2012-1997)= 15 years
∵We know that there is growth in value of object over multiple years.
∴Compound annual growth rate (CAGR)=
![[((end\ value)/(initial\ value) )^{(1)/(n) } ] -1](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ekzzwsxm1bv4pards6b872hosi3plyu0fx.png)
Remember, n = number of years
∴ Growth rate=
![[((9500)/(5000) )^{(1)/(15) } ]-1](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2jm48rbknubxdurww1sx4v7lihn4m665qx.png)
⇒Growth rate=
![[(1.9)^{(1)/(15) } -1]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dhppfsr3evtnule55is3o06smvqkcadl8j.png)
⇒Growth rate=

⇒ Growth rate= 0.0437
Now, finding percentage of growth rate
∴

∴ Annual growth percent over the period of time is 4.37%
