This appears to be a simple interest problem, as no compounding periods were noted.   Further, 30 months is simply 2.5 years.      To get the PV, take the FV/(1+i)n        PV = 10,000/(1.0209)2.5      PV =...

FV = PV * (1 + i)n   Problem is, this is compounded weekly, not annually.  So, we must make adjustments:      FV = 2,500 * (1 + 0.0219/52.5)52.5 * 2 = 105        FV = 2,500 (1.00041714285)105      ...

The interest rate is computed by the following:           n th root of (FV/PV)-1          Here, because of the bi-weekly, we adjust to the root being:  26*3 = 78            So, we take the...

P = [PV]/[1-(1+r)-n/r   P=Payment r=APR interest rate n=number of payment months Remember that for the denominator, we have to divide the APR by 12   P=[20,000]/[1-(1+0.001658)-6*12=-72/0.0199/12   P=  20000/[(1-0.8875426426)/(0.0199/12)   P=[20,000]/[(1-0...

Because this website doesn't seem to allow for editing, whenever formulas are involved, please see the work-out of a prior problem, involving the payments on a Toyota Camry. The correct formula for this, given the '^' symbol for exponents, has the following values: p=[150,000]/[1-(1+(0.0319/12)^-240)/(0...
