3. Suppose you bought a $60,000 truck which is 100% financed at 10% annual rate for 7 years.

a) How much will your monthly payments be?

b) What will be your total payment at the end of the 7 years?

c) After 7 years, how much of your total payment is interest?

I understand b) and c) but I can't firgure out a) first. I need someone to give the equation and how the values are placed. I have a scientific calculator, not a financial calculator.
