13. Question 34
Managers at Stars corporation, which sells Specialty T-shirts
decided that the demand function for their product can be
represented by the following equation:
Q = 200 -3P -2 Pr + 0.1 I
Where Q is the quantity demanded per month, P is the price of a
shirt, Pr is the price of a related product, and I is per capita
disposable income. The current values for these variables are Pr
=$12, and I= $5,000
As Pr =$12, and I= $5,000 so the demand function becomes,
Q = 200 -3P -2*12 + 0.1*5,000= 676-3P
a.If P =$10, how many shirts can the company sell per month?
Required number of sells,
Q = 676-3P=676-3*10 = 646
b.Given P = $10, what is the price elasticity of demand for
shirts?
We can see that,
Thus elasticity at P =$10 is
c.Given your answer in part b, what pricing recommendation
would you give the managers at Stars if they wish to increase
Total Revenues? Explain.
The answer in part b shows that the demand is Inelastic. Thus if
the price is increased the demand will decrease by less amount
hence to increase total revenue they should increase the price.
d. What would you need to calculate to find the impact of a
change in I on the quantity demanded for hats per month? How
would you interpret your calculations? Explain your answer.
We can calculate the elasticity of I (i.e. income elasticity) that

14. will tell us how much the income change is affecting the
demand change and based on that information we can process
forward.
Question 35
An electronics plant's production function is Q = 2LK, where Q
is its output rate, L is the amount of labor it uses per period,
and K is the amount of capital it uses per period. The price of
labor is $ 6 per unit of labor, and the price of capital is $4 per
unit of capital. The firm's vice president for manufacturing
hires you to determine which combination of inputs the plant
should use to produce 50 units of output per period.
a.What advice would you give him?i.e. how many units of
L and K should they hire? Explain to the vice president how you
would go about solving this problem. b. Suppose the price
of labor decreases to $5 per unit. Without doing any
calculations, what effect will this have on your
recommendation, if any?
a) 1st of all they want to produce 50 units of output thus,
Q = 2LK = 50
· LK = 25
Now as both L and K are integers thus there are only few
choices,
i. L = 1, K = 25 => Total cost = 1*6+25*4 = $106
ii. L = 5, K = 5=> Total cost = 5*6+5*4 = $50
iii. L=25, K = 1 => Total cost = 25*6+1*4 = $154

15. So we can see that for option ii the cost is minimum thus they
should hire 5 units of labor and 5 units of capital for
production.
b) If the price of labor decreases the cost of all options will
decrease but still we can clearly see that the option ii would be
the best choice in that case as well.
Question 37
Suppose that the market supply and demand equations for a
given
product are:
QD = 500 - 10P
QS = - 100 + 20P
Determine the equilibrium price and quantity for this market.
We know that at the equilibrium point,
QD = QS
Hence here at the equilibrium point,
500 - 10P = - 100 + 20P
· 30P = 600
· P=$20
· Q = 500-10P = 500-10*20 = 300
Thus equilibrium price is $20 and quantity is 300.
