1. P* and Q* are the equilibrium price and Quantity respectively. Equilibrium occurs at the point where demand and supply curve intersects. At this point, Qd = Qs
2. Let the demand and supply functions be as follows: (a) Qd-51 – 3P (6) Qd...
-------------------------------------------------------- #2 Find the equilibrium solution for each of the following models. A) Qd=Qs Qd=3-P^2 Qs=6P-4 B) Qd=Qs Qd=8-P^2 Qs=P^2-2 Plzzzzzzzzz answer all questions !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 5. if (b+ d) 0 in the linear market model, what can you conclude regarding the posi- tions of the demand and supply curves in Fig. 3.1 What can you conclude, then, regarding the equilibrium solution? FIGURE 3. (chard) (supply) p*
Exercise 3.2: Single Unknown 2. Let the demand and supply function be as follows: a) Q_d= 51 – 3P b) Q_d=30-2P Q_s=6P-10 Q_s=-6+5P Find P* and Q* by elimination of variables. (Use fractions rather than decimals) 4. If (b + d) =0 in the linear market model, can an equilibrium solution be found by using (3.4) and (3.5)? Why or why not?

18. Demand and Supply curves can be represented by: Qd = 90-2P; and Qs = 3P. Using the same Demand and Supply curves that can be represented by: Qd = 90-2P; and Qs = 3P. Consumer Surplus is: $1944 $342 $729 $486
17. Demand and Supply curves can be represented by: Qd = 90-2P; and Qs = 3P. Using the same Demand and Supply curves that can be represented by: Qd = 90-2P; and Qs = 3P. Producer Surplus is: $486 $243 $118 $900
industry supply and demand are given by QD=900-2P and QS=3P
Suppose demand and supply for food is given by 100 - 6P = Qd : Demand Curve Qs = 28 + 3P : Supply Curve ∃p = p* ∋qd = qs = q* What is the (marginal) willingness to pay for the 30th unit? What is the marginal additional cost for the 30th unit? Show on two separate graphs.
16 . Demand and Supply curves can be represented by: Qd = 90-2P; and Qs = 3P. Calculate the equilibrium price and quantity: P = $18; and Q = 54 P = $90; and Q = 45 P = $30; and Q = 54 P = $30; and Q = 30
1. Consider the following demand and supply functions for vitamins : Qd= 100 - 5P and Qs= 4 + 3P. Graph the supply and demand functions in the typical manner with price (P) on the Y-axis and quantity on the X-axis, showing their intercepts. What is the slope of each line? What is the equilibrium price and quantity?
CONSIDER THE FOLLOWING DEMAND AND SUPPLY FUNCTIONS FOR CORN: DEMAND IS GIVEN BY Qd corn = 15 -2P, SUPPLY IS GIVEN BY Qs corn = 5P -6. AT THE EQUILIBRIUM PRICE WHAT ARE THE ELASTICITIES OF DEMAND (Ed) and SUPPLY (Es )? Note in your calculations, round quantities to 1 decimal place and price. Ed = ? Es = ? Round your answers to 2 decimal places. Include any negative signs if necessary.
