P = 3400
r = \frac{0.04}{12}
n = 8

Step 1: Calculate the present value (cash price) using the annuity due formula:
PV = 3400 \times \frac{1 - (1 + \frac{0.04}{12})^{-8}}{\frac{0.04}{12}}

Step 2: Calculate \( (1 + \frac{0.04}{12})^{-8} \):
(1 + \frac{0.04}{12})^{-8} \approx 0.969198

Step 3: Plug in the value:
PV = 3400 \times \frac{1 - 0.969198}{0.003333}
PV = 3400 \times \frac{0.030802}{0.003333}
PV \approx 3400 \times 9.240
PV \approx 31,464

Step 4: Monthly payment is given as:
\text{Monthly Payment} = 3400

Final Result:
PV \approx 31,464.00
\text{Monthly Payment} = 3400.00
