Final answer:
The equity on a home loan can be calculated by subtracting the amount still owed to the bank from the current value of the home, which in this case is $250,000.
Step-by-step explanation:
To calculate the equity on a home loan, you subtract the amount still owed to the bank from the current value of the home. In this case, Freda bought a house for $150,000 in cash and the current value is $250,000. Since she owes zero to the bank, her equity is the whole $250,000.
Therefore, the answer is $250,000. This can be found in option B.
