Some time ago, julie purchased eleven acres of land costing $15,890. today, that land is valued at $34,686. how long has she owned this land if the price of the land has been increasing at 5 percent per year?

Julie purchased the acres 16 year ago

Explanation:

Imagine you are Julie at year cero about to purchase eleven acres of land. The seller tells you that in X amount of years it will value $34686 because it increases 5% each year. He also tells you that according to the Present Value formula, the eleven acres are worth today $15890.

The formula is:

PV=Ct/[(1+r)^n]

Ct= cash flow at t time

r= rate

n= period of time

To calculate how many years it will be worth $34686 you need to isolate n from the PV formula

n=[ln(Ct/PV)]/ln(1+r)

n=ln(34686/15890)/ln(1+0,05)

n=16
