To find the annual growth rate of the house's value between 1985 and 2005, we can use the formula for compound annual growth rate (CAGR):

$CAGR = \left( \frac{V_f}{V_i} \right)^{\frac{1}{t}} - 1$

Where:

• $V_f$ is the final value (in 2005), which is $149,000,
• $V_i$ is the initial value (in 1985), which is $108,000,
• $t$ is the time in years, which is $2005 - 1985 = 20$ years.

Substitute the values into the formula:

$CAGR = \left( \frac{149,000}{108,000} \right)^{\frac{1}{20}} - 1$

Now, let's calculate this.The annual growth rate (CAGR) of the house's value between 1985 and 2005 is approximately 1.62%.

2. If the house continues to grow at the same rate, what will its value be in 2025?
3. Can we calculate the future value of the house after 10 more years using the same growth rate?
4. How does inflation affect the interpretation of this growth rate over time?
5. What would be the total percentage increase in the house's value from 1985 to 2005?

Tip: The compound annual growth rate (CAGR) smooths out the effects of volatility over a period, showing the average growth rate per year.
