For Problems 5-7, help a Chinese auto manufacturer make calculations on some bonds. The company issues 935,000,000 yuan of 8% 15-year bonds to upgrade its assembly line. Terms of the bond require annual interest payments to bondholders plus annual deposits to a sinking fund for retirement of the bonds when they mature.

5) How much interest must the corporation pay to the bondholders each year?

A 74,800 yuan B 748,000 yuan C 7,480,000 yuan D 74,800,000 yuan

6) Assuming the corporation can earn 9% compounded annually on its sinking fund, how much must it deposit into the fund at the end of each year?

A 31,845,055.28 yuan B 34,435,642.52 yuan C 31,884,837.51 yuan D 29,215,647.04 yuan

7) What is the total amount the corporation needs each year to meet its obligations on the bonds?

A 106,645,055.28 yuan B 104,015,647.04 yuan C 109,235,642.52 yuan D 106,684,837.51 yuan

I do not want to cheat. When it comes to bonds I am struggling to understand where the above amounts match up to the TVM variables. Any help is appreciated :)
