Given:
Principal : 7,200
Interest Rate:
Bank M : 3%
Bank K : 4%
Term : 5 years
Interest = Principal Interest Rate term
Bank M:
I = 7,200 0.03 5
I = 1,080
Bank K:
I = 7,200 0.04 5
I = 1,440
1,440 - 1,080 = 360
Jim will pay 360 more interest if he takes the $7,200 loat at a 4% interest rate for a 5-year term.
