Warren Corporation's stock sells for $$42\mathrm{.}00$ per share. The company wants to sell some $20-$year, annual interest, $$1,000$ par value bonds. Each bond would have $95$ warrants attached to it$,$ each exercisable into one share of stock at an exercise price of $$47\mathrm{.}00.$ The firm's straight bonds yield $10\mathrm{.}6\%.$ Each warrant is expected to have a market value of $$2\mathrm{.}00$ given that the stock sells for $$42\mathrm{.}00.$ What coupon interest rate must the company set on the bonds in order to sell the bonds$-$with$-$warrants at par? Do not round your intermediate calculations.
