Description

"Discount Sale" PPT courseware of linear equation of one dollar

Several concepts in commodity sales:

1. Cost price: the price at which the goods are purchased (sometimes also called the purchase price).

2. List price: The price marked at the time of sale (sometimes called the original price, fixed price).

3. Selling price: the selling price when selling goods (sometimes called transaction price, selling price).

4. Profit: Net income in the process of selling goods, that is, profit = selling price – cost price

5. Profit rate: profit as a percentage of cost price, that is, profit rate = profit ÷ cost price × 100%

6. Discount: When selling goods, if the price is multiplied by a few tenths or a few percent, it is said that the price has been discounted. For example, if a certain type of clothing is given a 20% discount, it is sold at 80% of the price.

Basic exercises:

1. The price of a product is 50 yuan, and it is now sold at a 20% discount, and the selling price is ____ yuan; if the purchase price is 32 yuan, then his profit is ____ yuan, and the profit margin is ______.

2. The cost price of a watch is 70 yuan, and the profit margin is 30%. Then the profit of this watch is ____ yuan, and the selling price should be ____ yuan.

3. The original price of a mobile phone is 1,080 yuan. Now it is on sale. If the price is 810 yuan, the merchant will sell it at a ______ discount.

Improve ability:

A jacket is priced at a 50% increase in cost and then sold at a 20% discount due to the season. Each jacket is sold for 60 yuan. What is the cost of each jacket for this batch of jackets? Did the boss lose or make a profit? How much did you make? What was your profit margin?

Solution: Assume the cost price is x yuan, then the bid price is (1+50%) x yuan. According to the meaning of the question,

Get (1+50%)80% x =60

Solve for x=50

Profit = selling price - cost price

60-50 = 10(yuan)

Profit rate = profit ÷ cost price × 100%

Answer: The boss earned 10 yuan, and the profit margin was 20%.
