Mr. Sam buys RM8000 worth of home furnishings from the KingQueen House Deco. He pays RM1000 down and agrees to pay the balance with monthly payments over 5 years at 10% compounded monthly. The contract he signs stipulates that if he pays off the contract early there is penalty equal to three months payments.

He realizes that to do so means he will have to pay 2.5 months penalty on the KingQueen House Deco contract. Examine whether Mr.Sam should refinance or not.
