  Solution
Equity:
Number of shares outstanding = 1,000,000
 Market Value per share = $25
Market Value of Equity = Number of shares outstanding * Market Value per share
 Market Value of Equity = 1,000,000 * $25
 Market Value of Equity = $25,000,000
Debt:
Market Value of Debt = $35,000,000
Total Market Value of Firm = Market Value of Equity + Market Value of Debt
 Total Market Value of Firm = $25,000,000 + $35,000,000
 Total Market Value of Firm = $60,000,000
Weight of Equity = Market Value of Equity / Total Market Value of Firm
 Weight of Equity = $25,000,000 / $60,000,000
 Weight of Equity = 42%
Weight of Debt = Market Value of Debt / Total Market Value of Firm
 Weight of Debt = $35,000,000 / $60,000,000
 Weight of Debt = 58%
