In the public test subjects, the quantitative relationship is an important point of investigation. Among them, the issue of profit occupies an important position in the quantitative relationship.
Mastering the skills of solving the profit problem can not only improve the score of the line test, but also help the actual work. In this article, the Blue Fox Public Examination will introduce some preparation skills for the line test to help students better cope with the profit problem.
Before dealing with the issue of profit, let's first clarify some basic concepts. Profit refers to the net income obtained by a business or individual in the course of its business activities.
In a volume relationship, the issue of profit usually involves factors such as cost, selling price, and profit margin. In the following, we will analyze the solution to the profit problem with specific examples.
Let's say a store buys a batch of goods, and the cost of each item is 100 yuan. The store wants to ** the goods at a certain profit margin, and the selling price of the goods makes the store's profit margin 20%.
Analysis: Profit margin can be calculated using the formula, i.e., profit margin = (selling price - cost) cost. According to the title, the profit margin is 20%, the cost is 100 yuan, and the selling price is x yuan. Substituting the formula gives (selling price - 100) 100 = 02。Solving the equation can be obtained for a price of 150 yuan.
Blue Fox Public Exam Analysis: This question examines the calculation of the profit rate and the solution of the equation. To solve such problems, it is necessary to first understand the definition of the profit rate and master the method of solving the equation. By substituting and solving the equation, the correct answer can be obtained.
When a store sells a price of 150 yuan per item** and seeks a profit margin of 25% for the store, how much does it cost per item?
Analysis: Profit Margin = (Selling Price - Cost) Cost. According to the title, the profit margin is 25%, the selling price is 150 yuan, and the cost is X yuan. Substituting the formula, we get (150 - x) x = 025。Solving the equation can get a cost of 120 yuan.
Blue Fox Public Examination Analysis: This topic is also to examine the calculation of profit rate and the solution of equations. By substituting and solving the equation, the cost can be obtained as 120 yuan.
A store buys a batch of goods, and the cost of each item is 80 yuan. The store hopes to make a profit margin of 40% ** goods, and asks how much the price of the goods is
Analysis: Profit Margin = (Selling Price - Cost) Cost. According to the title, the profit margin is 40%, the cost is 80 yuan, and the selling price is x yuan. Substituting the formula, we get (x - 80) 80 = 04。Solving the equation can be obtained for a price of 112 yuan.
Blue Fox Public Examination Analysis: This question also examines the calculation of profit rate and the solution of equations. By substituting and solving the equation, the selling price can be obtained at 112 yuan.
A store buys a batch of goods, and the cost of each item is 120 yuan. The store hopes to make a profit of 30 yuan per item, and asks how much the product is sold for
Analysis: Profit = Selling Price - Cost. According to the title, the cost of each item is 120 yuan, the profit is 30 yuan, and the selling price is x yuan. Substituting the formula, we get 30 = x - 120. Solving the equation can be obtained for a price of 150 yuan.
Blue Fox Public Examination Analysis: This question examines the calculation of profit and the solution of equations. By substituting and solving the equation, the selling price can be obtained at 150 yuan.
A store buys a batch of goods, and the cost of each item is 50 yuan. What is the profit margin of the store at the price of 100 yuan per item?
Analysis: Profit Margin = (Selling Price - Cost) Cost. According to the title, the cost is 50 yuan, and the selling price is 100 yuan. Substituting the formula gives (100 - 50) 50 = 1. Solving the equation yields a profit of 100%.
Blue Fox Public Exam Analysis: This question examines the calculation of profit margin. By substituting the formula, the profit margin can be obtained by 100%.
When a store sells a price of 200 yuan per item** and finds the store's profit margin of 50%, how much does it cost per item?
Analysis: Profit Margin = (Selling Price - Cost) Cost. According to the title, the profit margin is 50%, the selling price is 200 yuan, and the cost is x yuan. Substituting the formula, we get (200 - x) x = 05。Solving the equation gives a cost of 13333 yuan.
Blue Fox Public Examination Analysis: This topic is also to examine the calculation of profit rate and the solution of equations. By substituting and solving the equation, we can get a cost of 13333 yuan.
A store sells each item at a price of 250 yuan**, hoping that each item can earn a profit of 50 yuan, and how much does each item cost?
Analysis: Profit = Selling Price - Cost. According to the title, the selling price is 250 yuan, the profit is 50 yuan, and the cost is x yuan. Substituting the formula, we get 50 = 250 - x. Solving the equation can get a cost of 200 yuan.
Blue Fox Public Examination Analysis: This question examines the calculation of profit and the solution of equations. By substituting and solving the equation, the cost can be obtained as 200 yuan.
