It is known that the demand function and supply function of a commodity are: QD = 14-3p, QS = 2 + 6p. What is the equilibrium price of the commodity? Specific calculation steps and instructions are required
Commodity balance is the balance of supply and demand. QD = QS, 14-3p = 2 + 6p, P = 4 / 3, so the price is 4 / 3
The demand function and supply function of a consumer for commodity X are QD = 14-3p and QS = 2 + 6p respectively. Try to calculate the equilibrium of the commodity
Equilibrium price refers to the price when the demand and supply of a commodity are equal. At this time, the demand price and supply price of the commodity are equal, which is called equilibrium price. Then, when QD = QS, P reaches the equilibrium price, and P = 1.33 calculated from 14-3p = 2 + 6p. Then p is substituted into the equation, and the obtained QD = QS = 10, and the equilibrium output is 10
Given that the demand function of a commodity is QD = 10-2p and the supply function is QS = 2 + 6p, the equilibrium price of the commodity is
Just solve the equation and let QD = QS
Then 10-2p = 2 + 6p
The solution is p = 1, q = 8
So the equilibrium price is 1
When an enterprise produces a product, its fixed cost is 1000 yuan, the variable cost per unit product is 18 yuan, and the market demand function is q = 90-p
If the price is p, the market demand q = 90-p, that is, so many units of products should be produced
Then the cost is 1000 + 18q
Sales amount is p * Q
Replace Q with (90-p) and get
Profit function w (P) = P * (90-p) - 1000-18 (90-p)
=-P^2+108P-2620
Thus, the optimal price and maximum profit can be further calculated

Assuming that the demand function and supply function of a perfectly competitive market are QD = 50000-2000p and QS = 40000 3000P respectively, what is the demand function of the manufacturer
Hello, in the perfectly competitive market, the demand function of the manufacturer is only in the market price, and the manufacturer can sell infinite products, so its demand function is the market price curve, parallel to the q-axis: simultaneous QD and QS, and the solution is p = 2, that is, D: P = 2
