P, L, and O are partners with capital balances of $50,000, $30,000 and $20,000 and who share in the profit and loss of the PLO partnership 30%, 20%, and 50%, respectively, when they agree to admit C for a 20% interest.

C contributes $10,000 to the partnership and the goodwill method is used. What will be the result of the goodwill calculation? (4 points)

The answer is Goodwill of $15,000 all to C. I need a detailed calculation as to how you get this number.
