First Calculate the interest payment of both as follow
Interest Payment = Total Installment Payment - Debt Value

Interest Payment = ( $400 per month x 10 years x 12 months per year ) - $20,000 = $48,000 - $20,000 = $28,000
Joe
Interest Payment = ( $645.34 per month x 10 years x 12 months per year ) - $40,000 = $77,440.8 - $40,000 = $37,440.8
Joe will pay more interest expense as compared to Sue.
