The initial cost of a solar energy system is $14,000. If this amount is paid with a 30% down payment and the balance is borrowed at 8% interest for 12 years, calculate the annual payments [A] and interest charges [B] for a market discount rate of 6%. Also estimate the present worth [C] of the annual payments.
Known information:
• Initial Cost (P) = $14,000.00
• Down Payment (% of P) = 30%
• Down Payment = $4200
• Loan Interest (i) = 8%
• Discount Rate (j)= 6%
