Suresh buys a new car for $56000. He pays $3500 down and the rest in 60 monthly payments (at the end of each month). The interest rate is 5% compounded 2 times per year. (All answers to 2 decimal places. But keep 5 decimal places for any intermediate calculations.)

a) How much is each monthly payment?

b) If he rounds his monthly payment up to the nearest $10, so his last payment will be a drop payment, what is his last payment?

c) If he rounds his monthly payment down to the nearest $10, so his last payment will be a balloon payment, what is his last payment?
