This payment is only to recover the price of the car and other charges are added too but they are not considered here. Another financing entity has advertised a fancy design for payment structurethat has attracted many customers. You have already paid for 1 full year to the current financing company and have to decide whether you want to change it to the new institution or not. They are offering 5 year loans with equal monthly payments with 1% monthly interest rate. However they allow customers no payment for the last month of the year and the first month of the year. Answer the following questions based on the fact that the only calculation tools that you have are tables for 0.75 and 1 percent interest rates with n values up to 12 and a simple calculator to perform addition, subtraction, multiplcation and division. No formula sheet or knowlege of them should be used.
  (1) How much is the monthly payment value of the current loan?
  (2) How much is the monthly payment value of the new loan?
