Question

Assume that demand for a commodity is represented by the equation P = 20 – 0.6 Q d, and supply by the equation P = 10 + 0.2 Qs where Qd and Q s are quantity demanded and quantity supplied, respectively, and P is the Price. Use the equilibrium condition Qs = Qd

1: Solve the equations to determine equilibrium price.

2: Now determine equilibrium quantity.

3: Graph the two equations to substantiate your answers and label these two graphs as D1 and S1.

4: Furthermore; using demand and supply show what happen to equilibrium price and quantity if eating this product causes cardiac problem.

Answer #1

1) Market quantity is determined at

20 - 0.6Q = 10 + 0.2Q

10 = 0.8Q

Q = 10/0.8 = 12.5 units

P = 10 + 0.2*12.5 = $12.5 per unit

2) Quantity is 12.5 units

3) Graph is shown below

4) If there is negative news about the product, then its demand would decrease. This is because consumers would reduce its consumption at every price. This shifts the demand curve leftwards and price and quantity both decline

Q4. Assume that demand for a commodity is represented
by the equation
P = 10 - 0.2Qd
and supply by the equation
P = 2 + 0.2Qs,
where Qd and Qs are quantity demanded and quantity supplied,
respectively ,and P is
price. Using the equilibrium condition Qs = Qd, solve the equations
to determine equilibrium
price and equilibrium quantity. Graph the two equations to
substantiate your answers. Answer
in the space below!

Assume that the demand for a commodity is represented by the
equation Qd = 300-50P and supply by the equation Qs= -100+150P
where Qd and Qs are quantity demanded and quantity supplied,
respectively, and P is price. Using equilibrium condition Qd = Qs,
solve the equation to determine equilibrium price and quantity.

Assume that demand for a commodity is represented by
the equation P = 30 - 0.4Qd and supply by the equation P = 6 +
0.2Qs, where Qd and Qs are quantity demanded and quantity supplied,
respectively and P is price. The market will clear
at
A
P = 14 and Q = 40.
B
P = 40 and Q = 14.
C
P = 20 and Q = 6.
D
P = 6 and Q = 20.

Assume that demand for a commodity is represented by the
equation P = 10 - 0.2Q and supply by the equation
P = 2 + 0.2Q. Find equilibrium price and quantity
(algebraically). Then graph the supply and demand lines, plot
equilibrium point and label axes, equilibrium P* and Q*, vertical
and horizontal intercepts for demand curve, and vertical intercept
for the supply curve.

Consider a market that can be represented by a linear demand
curve, QD = 200 – 2PD, (where QD is the quantity demanded and PD is
the price that demanders pay) and a linear supply curve that QS = ½
PS (where QS is the quantity supplied and PS is the price that
suppliers get).
a. What is the equilibrium price?
b. What is the equilibrium quantity?
c. What is demand elasticity at the equilibrium point?
