Find the present values of the following cash flow streams. The appropriate interest rate is $12\%.($Hint: It is fairly easy to work this problem dealing with the individual cash flows. However, if you have a financial calculator, read the section of the manual that describes how to enter cash flows such as the ones in this problem. This will take a little time, but the investment will pay huge dividends throughout the course. Note that, when working with the calculator's cash flow register, you must enter CF$0=0.$ Note also that it is quite easy to work the problem with Excel, using procedures described in the Ch$04$ Tool Kit.xlsx$.)$ Do not round intermediate calculations. Round your answers to the nearest cent.
