hello! i hope u can help me with this question :( im having trouble with it!!

question:

The market value of the assets of a corporation is currently $290.0 million but the owners wish to only use as collateral a value that will result in an interest rate of about 10%. The firm has on issue a debt outstanding that has a par value of $35.0 million and a due date of exactly five years. No intermediate interest payments are required. The risk-free (continuous) rate is 3.25% and the standard deviation of returns of the firm's assets is 60%.

What is the value of the assets required by the debt holders to permit a fair interest rate of approximately 10% (answer should ensure that the fair interest rate is in the range of >9% and <11%)
