What does it mean when a question asks "Calculate the nominal amount of a bond which can be purchased using the current bank account balance of $65,000."

This bond pays 6% p.a. half-yearly coupons, redeemed on any coupon date 15-20 years from now (at decision of issuer), and has a minimum gross yield of 9% p.a.

I'd like to know how to do this question, rather than just the answer. Thanks!
