Assuming that she puts 20% down, what will be her monthly payment and the total cost of interest over the cost of the loan for each assumption? (Use the Table 15.1) Note: Do not round intermediate calculations. Round your answers to the nearest cent. e. What is the savings in interest cost between 3% and 4% ? Note: Round your answer to the nearest dollar amount. f. If Harriet uses 30 years instead of 25 for both 3% and 4%, what is the difference in interest? Note: Use 360 days a year. Round your answer to the nearest dollar amount. Harriet Marcus is concerned about the financing of a home. She saw a small cottage that sells for $50,000.
