"Discount Sales" One Yuan Square Equation PPT Courseware 3
Description
"Discount Sales" One Yuan Square Equation PPT Courseware 3
What's going on with the discount?
The so-called discount means that the goods are sold at a certain proportion of the price based on the marked price. It is a promotional behavior by merchants.
For example:
A skateboard is priced at 200 yuan. If it is sold at a 10% discount, the actual selling price is 200 × 0.9 = 180 (yuan). If it is sold at a 30% discount, the actual selling price is 200 × 0.7 = 140 (yuan).
2. Profit and profit rate
Profit: a represents the selling price, b represents the cost (purchase price), and P represents profit. The relationship between the three is: P= a - b
Total profit: P represents profit, m represents the quantity sold, and W represents total profit. The relationship between the three is:
W = Pm = m (a-b)
Profit rate = profit / cost
summary
1. Through the discussion and research on discount sales issues, we know the meaning of concepts such as cost, price, selling price, discount, profit, profit rate, price increase, price reduction, etc.
