Answer: Annual rate of growth is 5.18%.
Explanation:
Since we have given that
In 1968, Bryan purchased a Corvette = $4600
In 2018, Corvette now has an appraised = $57500
According to question, we need to find the annual growth rate:
As we know the formula for "Compound interest":
![A=P(1+(r)/(100))^n\\\\57500=4600(1+(r)/(100))^(50)\\\\(57500)/(4600)=(1+(r)/(100))^(50)\\\\12.5=(1+(r)/(100))^(50)\\\\r=5.18\%](https://img.qammunity.org/2019/formulas/mathematics/middle-school/t3c4vsuk582yxwdkzzlfcy9ki58oyzdz4c.png)
Hence, Annual rate of growth is 5.18%.
