7. An investor is considering an investment that will pay $2,150 at the end of each year for the next 10 years. He expects to earn a return of 12 percent on his investment, compounded annually. How much should he pay today for the investment? How much should he pay if the investment returns are received at the beginning of each year?

If possible could you explain how to solve this using a financial calculator (BA II PLUS) :)
