7. Deborah invested $3000 into a fund that is expected to earn 8.2% per year. If you use the Rule of 72, about how long will it

Stella [2.4K]

Answer:

About 9 years

Step-by-step explanation:

The rule of 72 tells us that the amount of time it takes to double your investment is 72 divided by the interest rate.

<em>To get an approximation, we round of interest rate of 8.2% to 8% and then use the rule.</em>

Time = $\frac{72}{8}=9$

For deborah's investment of $3000 to go to $6000, it would take around 9 years.
