A loan of $100,000 is made today. This loan will be repaid by 10 level repayments, followed by a final smaller repayment, i.e.,
lawyer [7]

Answer:

p = $ 12521.82

Step-by-step explanation:

Interest Rate = 3.6 %, Compounding Frequency: Semi-Annual, Equivalent Annual Interest Rate = [1+\frac{0.036}{2}]^(2) - 1 = 0.0363 or 3.63 %

Number of Repayments is 11 with 10 being equal in magnitude and the last one being worth $ 270, the first repayment comes at the end of Year 2

Let  $ p  be the  level payments that required. Therefore,

100000 = p\times  \frac{1}{0.0363} \times [1-\frac{1}{(1.0363)^{10}}] \times \frac{1}{(1.0363)} + \frac{270}{(1.0363)^{12}}

100,000 - 176.01 = p x 7.972

p = $ 12521.82
