HYT has 2178.9 mil in assets, 654.9 mil in debt, and 1,524 mil in equity. Their leverage ratio .30056 or 30.056%

Show all work please I'm super confused with this question.

c) HYT invests primarily in high-yield (and therefore high-risk) bonds. Assume these bonds pay an average of 8%, and assume HYT acquires debt at an interest cost of 1.5%. If you invest in the fund, what is your expected annual percent return net of the interest costs? Use the leverage from part b and calculate on a portfolio basis instead of a per-share basis (this will make it easier to deal with interest costs)
