Answer
To find the annual growth rate of the comic book's value, we need to look at the function \(V(t)=1.50(1.17)^{t}\). The function represents exponential growth, where the base of the exponent,
, indicates the growth factor per year.The growth factor can be converted to a percentage growth rate by subtracting 1 from the growth factor and then multiplying by 100. This is because the growth factor includes the original amount (100%) plus the percentage increase.Let's calculate the annual growth rate:
To find the growth rate as a percentage, subtract 1 from the growth factor:
Therefore, the annual growth rate of the comic book is **17%**.
