You want to buy a new sports car, but you won't be able to afford it for $5$ years. You're looking at a model that currently costs $$80,245\mathrm{.}10,$ and the price is expected to rise by $4\mathrm{.}5\%$ per year until you are ready to buy it in $5$ years. When you're ready to buy the car, the local bank will give you a $5-$year loan at an annual interest rate of $10\%,$ with a $10\%$ down payment required. How much will the monthly payments be$?$
