Final answer:
The original list price of the freezer is $461.31. If the invoice is paid on September 1, the amount is $2059.24; if paid on September 13, it is $2168.98; and if paid on October 15, the full amount of $2190.89 is to be paid.
Step-by-step explanation:
To determine the list price of the freezer, we need to know that the sale price represents 84% (100% - 16% discount) of the list price. By dividing the sale price by 0.84, we can find the original list price. The payments for the invoice depend on the payment date and the discounts applicable if paid within certain time frames.
Calculation for the list price of the freezer:
List price = Sale price / (1 - discount rate)
List price = $387.50 / (1 - 0.16)
List price = $387.50 / 0.84
List price = $461.309523
Rounded list price = $461.31
Invoice Payments:
Payment on September 1 (within 15 days, hence 6% discount):
Payment = Invoice amount * (1 - discount rate)
Payment = $2190.89 * (1 - 0.06)
Payment = $2059.2366
Rounded payment = $2059.24
Payment on September 13 (within 30 days, hence 1% discount):
Payment = Invoice amount * (1 - discount rate)
Payment = $2190.89 * (1 - 0.01)
Payment = $2168.9811
Rounded payment = $2168.98
Payment on October 15 (no discount, beyond terms):
Full Invoice amount = $2190.89
