1. Problem Description

The problem describes two invoices, V 610 and AV 611, issued by Monsieur ERIC to his client CLAIRE. We need to calculate the final amount due for each invoice, considering discounts, rebates, and transport costs.

2. Solution Steps

Invoice V 610:

* Gross amount (HT): 1,500,000 F

* Discount: 10%

* Transport cost: 85,000 F

* Cash discount: 2% if paid within 8 days

First, calculate the discount amount:

$Discount = 1,500,000 \times 0.10 = 150,000 F$

Next, calculate the amount after discount:

$Amount\,after\,discount = 1,500,000 - 150,000 = 1,350,000 F$

Then, add the transport cost:

$Amount\,before\,cash\,discount = 1,350,000 + 85,000 = 1,435,000 F$

Finally, calculate the cash discount (2%) if paid within 8 days:

$Cash\,discount = 1,435,000 \times 0.02 = 28,700 F$

$Amount\,due\,with\,cash\,discount = 1,435,000 - 28,700 = 1,406,300 F$

$Amount\,due\,without\,cash\,discount = 1,435,000 F$

Invoice AV 611:

* Gross amount (FHT): 750,000 F

* Rebate: 5%

* Reimbursement of transport costs: 25,000 F

First, calculate the rebate amount:

$Rebate = 750,000 \times 0.05 = 37,500 F$

Next, calculate the amount after rebate:

$Amount\,after\,rebate = 750,000 - 37,500 = 712,500 F$

Since CLAIRE is reimbursed for 25,000 F of transport costs:

$Amount\,due = 712,500 - 25,000 = 687,500 F$

3. Final Answer

Invoice V 610: Amount due is 1,435,000 F. If paid within 8 days, a 2% cash discount applies, resulting in an amount due of 1,406,300 F.

Invoice AV 611: Amount due is 687,500 F.
