7. In purchasing a condominium, the amount of the loan is $176,000, the loan is for 30 years, and payments will be made monthly starting one month from now. If interest on the loan is 1% per month compounded monthly, how much is: a). the monthly payment? (10 points) b). the principal paid on the 20th monthly payment? (10 points) c). the interest paid on the 20th monthly payment? (5 points) (Note: You cannot use interest tables for this problem because the tables only go up through n = 100.)
