A retirement home at Deer Trail Estates now costs $185,000. Inflation is expected to cause this price to increase at 6% annually over the next 20 years. How large an equal, annual, end-of-year deposit must be made each year into an account paying an annual interest rate of 10% for the purchaser to have enough cash to purchase the home in 20 years? (Note that the rate of inflation compounds just like any other rate.) I need the calculator formula for this, please
