2. The salesperson offers, "Buy this new car for $25,000 cash or, with appropriate down payment, pay $500 per month for 48 months at 8% interest." Assuming that the salesperson does not offer a free lunch, calculate the "appropriate" down payment. A. $8,000.00 B. $4,520.64 C. $5,127.24 D. $1,000.00

Respuesta :

Answer:

B. $4,520.64

Explanation:

The computation of the down payment is shown below:

= {Monthly payment × (1 - 1 + interest rate)^-number of periods} ÷ {Interest Rate}

where,

Interest Rate = 8% ÷ 12 months = 0.66667

= {500 × (1 - 1 + 0.67)^-48} ÷ {0.67}

After solving this, the amount is $20,480.956

Now the down payment is

= $25,000 - $20,480.956

= $4,519.04 approx

The appropriate down payment that the salesperson would ask for would be B. $4,520.64.

The down payment would be the difference between the present value of the monthly payments and the cash price.

The present value of the monthly payments is:

= Amount x (1 - ( 1 + r) ^-number of periods) / rate

Rate = 8% / 12 months

= 8/12% per month

Present value will be:

= 500 x ( 1 - ( 1 + 8/12%)⁻⁴⁸ )/ 8/12%

= $20,480.956

Down payment:
= 25,000 - 20,480.956

= $4,520.64

In conclusion, option B is correct.
