Final answer:
The net cost of purchasing the vehicle is $17,327.20.
Step-by-step explanation:
To calculate the net cost of purchasing the vehicle, we need to consider several factors:
- Calculate the sales tax by multiplying the price of the car by the sales tax rate: $20,000 x 10.25% = $2,050.
- Compute the interest lost or foregone over the 36-month term. Multiply the down payment by the interest rate for each month, then subtract the security deposit at the end: ($2,000 x 0.04/12) x 36 - $500 = $240.
- Compute the interest paid on the loan for 36 months. Multiply the purchase payment by the interest rate for each month: $360 x 0.09 x 36 = $1,037.20.
- Subtract the resale/trade-in value from the net cost: $20,000 + $2,050 + $240 + $1,037.20 - $6,000 = $17,327.20.
Therefore, the net cost of purchasing the vehicle is $17,327.20.
