Kendra takes out a 5 year mortgage for $275,000. The term is 5 years and the amortization period is 10 years. The interest rate is i⁽¹²⁾ = 7.850%, and she makes monthly payments. How long (how many payments) until more of her monthly payment is going to Principal Reduction than is going to Interest? (i.e when is the first time t with PR_t> I_t?)
