4. a. Normal goods
Goods which demand tends to increase as income increases. Example : luxurious
cars.

b. Inferior goods
goods that demand tends to fall as income increases.

c. Substitutes Goods
items can be interchangeable, when a single price rises, demand for other goods
will rise.

d. Complementary Goods
a decline in goods prices causes an increase in demand for other goods.

5.demand curve has a negative slope due to the demand made by the buyer.buyers will
buy more goods if the goods are much cheaper price. so the price and quantity in
demand has a negative relationship. (mathematical explanation)

supply curve has a positive slope because that its offering is a Producer, so the
Producer will sell more goods when the price increased to greater profits.

6. Equilibrium is a condition where the amount of goods demanded equals the quantity
of goods offered. Equilibrium occurs when Qd=Qs

7. equilibrium :
QDx = QSx
8000-1000p = -4000 + 2000 p
12.000 = 3000p
P = $4

Q = 8000-1000p
Q = 8000-1000 ($4)
Q = 8000-4000
Q = 4000

Jadi Pe (equilibrium) = $4
dan Qe (Equilibrium) = 4000

dan titik keseimbangan terletak di Qe ; Pe (4000 ; $4)
