Part 4. Let's buy a car? - Prof. Business decides to buy a 2022 Honda CR-V Touring edition. After paying a down payment and taxes, Prof. Business can finance the rest of the purchase price with a loan of $22,000 for 48 months at a special finance rate offered by Honda of 2.9% APR compounded monthly. - Prof. Business finds out that Honda has a second offer of $1000 cash back (which will be used as an additional down payment) in place of the special 2.9% finance rate offered. Prof. Business can get 4.29% APR financing online for 48 months with the $1000 cash back offer. Answer the following questions. 1. What is the effective annual rate for each loan? 2.

The local Honda dealer has found a special 3.19% APR loan rate for 48 months from Citibank that Prof. Business qualifies for if he elects the $1000 cash back option. Finance says that's great: What would be the monthly payment under this loan? 7. Prof. Business is more than happy with the 3.19% APR and $1000 cash back offer but wants a monthly payment of $425 (assume a 48 -month loan term) and realizes he will have to put more money down. How much additional money will Prof. Finance have to put down in order to
