Given:
Principal /loan: 45,000
Interest rate: 5% per annum
Term: 6 years.
Simple Interest = Principal * interest rate * term
Simple Interest = 45,000 * 5% * 6
Simple Interest = 13,500
45,000 + 13,500 = 58,500 This is the total amount due
12 months * 6 years = 72 months
58,500 / 72 = 812.50 monthly payment
Kim must pay $812.50 per month for the next 6 years.
