A coincoin sold for $264 in 1977 and was sold again in 1989 for $475. Assume that the growth in the value V of the collector's item was exponential. Find the value k of the exponential growth rate. Assume Vo=264.

The exponential growth rate=k=0.0489

Explanation:

The formula we are going to use is:

Where:

V is the final value

V_o is the initial value

K is the exponential growth

t is the time

In our case:

V=475

V_o=264

t=12 years

Required:

The exponential growth rate=k=?

Solution:

The exponential growth rate=k=0.0489
