Calculate the equity each of these people has in his or her home:

A) Fred just bought a house for $200,000 by putting 10% as a down payment and borrowing the rest from the bank.

B) Freda bought a house for $150,000 in cash, but if she were to sell it now, it would sell for $250,000.

C) Frank bought a house for $100,000. He put 20% down and borrowed the rest from the bank. However, the value of the house has now increased to $160,000 and he has paid off $20,000 of the bank loan.
