A young worker has started to save for retirement. She has heard that investing in the stock market for the long term is her best option. Annual growth in the stock market over many decades has averaged about 6% per year, though this is not a constant growth rate.

Assuming that the growth rate is constant, create a model for the value of an investment that was made in the stock market several decades ago.

Write an exponential equation to represent the time t for a $10,000 investment in the stock market to be worth $100,000.

How long will it take for the investment to be worth $100,000? Solve the equation you wrote in #9. Justify each step. Round your answer to the nearest hundredth.
