[tex] \frac{PMT {((1 + i)}^{n} - 1)}{i( {1 + i)}^{n} } = PV[/tex]
PV is the loan amount
PMT is yearly payment
i is the interest rate per year in decimal form
(interest rate percentage divided by 1)
n is the number of years
PMT = 25,000
i = 10% = 0.1
n = 6 years
[tex] \: \: \: PV = \frac{25,000 ((1 + 0.1)⁶ - 1)}{0.1(1 + 0.1)^{6} } [/tex]
[tex] \: \: \: PV = 108,881.52[/tex]
