Given that Qd = 10 - 2p while Qs = 5 + 3P, if P = N 1 determine the equilibrium quantity.

A.

7

B.

6

C.

5

D.

8

Correct answer is D

To get equilibrium price and quantity:


i) Get function solved for Qs and Qd (quantity supplied) and Qd (quantity demanded)
ii) Set Qs equal to Qd
iii) Solve for P (equilibrium price)
iv) Plug your P back into your Qs and Qd function to get the quantity.


when, Qd = 10 − 2p and Qs = 5 + 3p
if Qd = Qs then,
10 − 2p = 5 + 3p
solving for p: 10 − 5 = 3p + 2p
5 = 5p
p = 1 (given in the equation)


Equilibrium Quantity will be gotten by plugging P into Qd and Qs respectively;

If P = 1
Qd = 10 − 2p Qs = 5 + 2p
= 10 − 2(1) = 5 + 3(1)
= 10 − 2 = 5 + 3
= 8

Given that the total production of Bandako farmers with one worker is 10kg. When the workers increased to 2, 3, and 4, the total production increases to 20, 36 and 60kg respectively.

Calculate the average product (AP) of the 4th unit of labour.

A.

20

B.

13

C.

15

D.

10

Correct answer is C

In this case, 4 workers produce 60kg of output therefore, the Average product of labour for the 3rd unit is 15kg. Given by:
Average product = Total product/Variable product

= 60/4
= 15kg
