Explanation / Answer

Amount financed is correct

time period = 4 years or 48 months

monthly rate = rate(48,775,-30060)

Effective annual rate = (1 + monthly rate)12 - 1 = 11.43%

interest rate = 6%

monthly interest rate = 6%/12

New payment amount = pmt(6%/12, 48, -30060) = $705.96

Time period = 5 years or 60 months

monthly interest rate = 6%/12

New payment amount = pmt(6%/12, 60, -30060) = $581.14

Payment = $500 per month

monthly interest rate = 6%/12, time period = 60 months

Amount financed = pv(6%/12,60,-500) = $25862.78
