A retail outlet purchased 300 printers at a list price of $100 less 7%, and 6%. The rate of markup on selling price on the printers was 40%. After selling 40% of the shipment, the rest of the printers were marked down to a reduced selling price. When there were only 40 printers left, the outlet marked these down to $76

84.23 x 399 - 26.226

Markup = 40%

This is all I can figure out..

Hmmm. What does "list price of $100 less 7%, and 6%" mean? Two successive discounts?

Also, after all the explanation, I don't see an actual question? What is it you are trying to calculate?

To solve this question, we need to follow a step-by-step approach. Let's break down the information given to find the answer.

1. Calculate the purchase price:
The retail outlet purchased 300 printers at a list price of $100 less 7% and 6%. To find the purchase price of each printer, we subtract the percentage discounts from the list price:

Purchase price = List price - (List price x Discount %1) - (List price x Discount %2)
= $100 - ($100 x 7%) - ($100 x 6%)

2. Calculate the markup on the selling price:
The markup is given as 40%, which means the selling price is 140% of the purchase price. To calculate the selling price, we multiply the purchase price by 140%:

Selling price = Purchase price x 140%

3. Calculate the selling price of the first 40% of the shipment:
Since 40% of the printers were sold at the markup price, we multiply the selling price calculated above by 40% to find the total revenue from these sales.

Revenue from first 40% = Selling price x 40%

4. Calculate the selling price for the remaining 60% of the shipment:
The remaining printers were marked down to a reduced selling price. We know that when there were only 40 printers left, they were marked down to $76 each. To find the reduced selling price, we need to calculate the average selling price of the previous sales.

Average selling price = Revenue from first 40% / (Total number of printers - Remaining number of printers)
= Revenue from first 40% / (300 - 40)

5. Calculate the revenue from the remaining 60%:
To find the remaining revenue, we multiply the reduced selling price by the number of remaining printers.

Revenue from remaining 60% = Average selling price x Remaining number of printers

Now that we have all the necessary calculations, we can find the total revenue:

Total revenue = Revenue from first 40% + Revenue from remaining 60%

I hope this helps you understand the problem and the steps to find the answer. Let me know if you have any further questions!
