Question1

 Price (P) Quantity Demanded (Qd) Total Revenue (TR) 10 1 10 9 2 18 8 3 24 7 4 28 6 5 30 5 6 30 4 7 28 3 8 24 2 9 18 1 10 10

Theprice elasticity of the demand is 1 throughout the length of thegraph. The graph has a constant gradient of 1 as shown in the graphabove.

Question2

Anincrease in the bus fare would increase its revenue. For an inelasticdemand curve a change in the price of a commodity does not affect thequantity demanded. With an increased price of commodity and no changein quantity demanded RTA is bound to have increased revenue.

Asshown in the graph above a change in the price causes a very smallchange in the quantity demanded

Question3

Anincreased technological improvement in a way to surpass thewillingness and ability to purchase a laptop would imply that thedemand curve shifts to the right. A shift in the demand curve to theright would imply that the equilibrium price rises as shown in thediagram below

Ashift of the demand curve from D1D1 to D2D2 causes the equilibriumpoint to rise from point E1 to point E2.

Question4

Amarket may be a place or forum by which buyers and sellers meet totrade goods and services for other goods services or money.Equilibrium occurs in a market where the quantity demanded by thebuyers balances the quantity supplied to the market. Thecorresponding price to this point is called the equilibrium pricewhile the corresponding quantity is known as the equilibrium quantity

Atequilibrium point the quantity demanded equals quantity supplied
