Harriet Marcus is concerned about the financing of a home. She saw a small cottage that sells for $40,000. Assuming that she puts 30% 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(a) and Table 15.1(b)). (Round intermediate calculations to 2 decimal places. Round your final answers to the nearest cent.)

		Monthly payment	Total cost of interest
a.	25 Years, 10.5%
b.	25 Years, 11.5%
c.	25 Years, 12.5%
d.	25 Years, 14%

e. What is the savings in interest cost between 10.5% and 14%? (Round intermediate calculations to 2 decimal places. Round your answer to the nearest dollar amount.)

F. If Harriet uses 30 years instead of 25 for both 10.5% and 14%, what is the difference in interest? (Use 360 days a year. Round intermediate calculations to 2 decimal places. Round your answer to the nearest dollar amount.)
