Occam Industrial Machines issued $225,000$ zero coupon bonds five years ago. The bonds originally had $30$ years to maturity with a yield to maturity of $5\mathrm{.}2$ percent. Interest rates have recently decreased, and the bonds now have a yield to maturity of $4\mathrm{.}6$ percent. The bonds have a par value of $$1,000$ and semiannual compounding. If the company has a market value of equity of $$120$ million, what weight should it use for debt when calculating the cost of capital?
