can you please help me with the c

Suppose the form structure of risk tree interest rates is as shown below. Term 2 yr 3 yr 7 10 20 y Rate (EAR %) 1.99 2.35 263 3.35 3.73 4.28 5.07 a. Calculate the present value of an investment that pays $2,500 in two years and $2,000 in five years for certain b. Calculate the present value of receiving $600 per year with certainty at the end of the next five years. To find the rates for the missing years in the table, Incany Worpolate between the years for which you do now the rates For Card the rate in year 4 would be the average rate in year 3 and year 5.) c. Calculate the present value of receiving $2.800 per year with certainty, for the next 20 years. Infer rates for the missing years using in interpolation in Use a spreadsheet) a. Calolate the present value of an investment that pays $2.500 in two years and $2.000 in five years for contain The present value of the investment is $4052.715. (Round to the nearest dollar) b. Calculate the present value of receiving 5600 per year with certainty, at the end of the next five years. To find the roles in the missing years in the table, inary interpolate between the years for which you to know the rate (for example, the rate in year 4 would be the average rate in year and your 5) The present value of the investment is $2758.2012. (Round to the nearest dollar) c. Calculate the present value of receiving $2.800 per year with certainty, for the next 20 years. Informaties for the missing years using linearnerpolation. (Hint Use a spreadsheet) The present value of the investment is $32209.66. (Round to the nearest dollar)
