Jack has just graduated and decided to buy a new car. He is thinking of buying a new Porsche and he estimates that he can get a good deal for $120,000. Assume that: he buys the car on finance with 6% annual interest rate within a 5-year plan. 1. Calculate the monthly repayment for such a loan. (integer number) 2. Calculate the total repayments for two years (use integer number and round to nearest thousands XX000) 3. Furthermore, the car attracts $2000 annually for registration and insurance (a conservative estimation) and $100 per week running cost. How much will he spend in the first two years excluding car payments? (integer number) 4. Jack wish the analyse the scenario that he will return the car after two years (without any accident) where the car at that point will worth $70,000. Based on the remaining repayments, calculate how much extra Jack needs to pay to the dealer. (round to nearest thousands X000)
