The formula for calculating a month's product sales is as follows: For example: Product a, sales price 30 yuan, cost price 10 yuan In May 2008, 5000 customers were sold and 20 customers returned In June 2008, 5500 were sold, 100 were returned by customers, and 10 of 20 were returned in May In July 2008, there were 0 sales, 0 customer returns and 0 replenishment In August 2008, there were 0 sales, 10 customer returns and 110 returns before replenishment In September 2008, 1000 were sold, 0 were returned by customers, and 10 were returned in August It is now required that: 1. What is the monthly sales volume from May to September, how to calculate it, and what is the formula? 2. What is the gross profit of sales from May to September? What is the formula? 3. To calculate the total sales and gross profit in June and July, we need a formula 6. Calculate the total sales and gross profit of 5 - 9 in the five months I don't understand this aspect, I hope you don't laugh, please give me more advice!

1. Monthly sales = (monthly sales quantity customer returns) × sales price
2. Gross profit of sales = sales cost
According to your question, it is estimated that the problem of return is how to calculate the sales in the previous month
Since the sales volume has been calculated in the previous month, the cost has been carried forward
Therefore, the return behavior in the following month will be withdrawn directly from the sales of the current month
May sales = (5000-20) × 30 = 149400
Gross profit = (5000-20) (30-10) = 99600
June sales = (5000-100 + 10) × 30 = 147300
July = 0
August sales = (110-10) × 30 = 3000
September sales = (1000 + 10) * 30 = 30300
Total sales from May to September = 330000
As the cost and selling price remain unchanged, the monthly gross profit rate will remain unchanged, which is 2 / 3 of the sales volume
5-9 gross profit = 220000

How to calculate the unit cost in the product sales cost calculation table? Is there a calculation formula
In the product sales cost calculation table, how to calculate the unit cost and how to get the product receipt document? There is no product purchase, only material purchase

The unit cost of a product is the total cost (including direct material, direct labor, manufacturing expenses, etc.) divided by the number of products produced
The quantity on the product warehousing list is the quantity of workshop production warehousing. Industrial enterprises use materials to produce products. This is the difference between industry and commerce

What is the formula for calculating the actual cost of goods sold according to the retail price method?

At the end of the period, the price difference of the goods sold should be calculated according to the following method: price difference rate = (price difference of the goods in stock at the beginning of the period + price difference of the goods purchased in the current period) / (price difference of the goods in stock at the beginning of the period + price difference of the goods purchased in the current period) × 100% price difference of the goods sold in the current month = the "main business income" of the current month

In the trial sale, it is found that the daily sales volume (m) of this kind of commodity is equal to the sales price (x) of each piece
In the trial sale, it is found that the relationship between the daily sales volume (m) of this commodity and the sales price (x) of each commodity is m = 140-x
(1) Write the function between the daily sales profit y and the sales price X
(2) If shopping malls want to get the maximum sales profit every day, what is the most appropriate price for each commodity? What is the maximum sales profit?
The second question needs a little process!

First question:
y=m(x-20)
=(140-x)(x-20)
=-x^2+160x-2800
Second question:
y=3600-(x-80)^2
When the selling price is 80 yuan, the profit is 3600 yuan
