You are saving to buy a cabin in the woods. You want to save $140,000 by 12 years from today. A savings account has an annual effective rate of 6%. You will contribute $6,000 today. Each year thereafter you will contribute an amount that is 3% higher than the year before, so that a year from today you will contribute an amount that is 3% higher than what you contributed today, and so forth and so on. You will calculate if you have saved enough. Is this a PV or an FV problem?
