Use the information in the aforementioned table to:
Calculate the equilibrium price. (3 markings)
Calculate the equilibrium quantity demanded and quantity offered and present the info graphically. (6 marks)
With the aid of a diagram, explain the difference between a change in the supply and a activity along the resource curve. (6 grades)
Explain four (4) factors that cause the demand curve to move for a coral mobile. (6 marks)
Shift in Supply vs. Movement along the Source Curve.
If one of the determinant of price changes it triggers the supply curve to shift but if none of the determinants apart from price changes causes a movement across the resource curve.
These other determinants are:
Cost of production
Profitability of related products
Profitability of goods in joint supply
Nature and other unpredictable events
Expectations future price changes.
The difference between a motion along the source curve and a shift of the resource curve is usually distinguished between a big change in resource and a change in quantity supplied.
If the other determinants of supply causes supply to go up the supply curve will switch to the right. The brand new curve (S1) demonstrates each price more Oxford pencils will be supplied.
If the other determinants cause resource to show up, the supply curve will change left. The new curve (S2) implies that at each price less Oxford pencils will be offered.
Factors that Cause the demand Curve to change for a coral telephone.
Four (4) factors that cause the demand curve to switch for a coral cellphone are:
Income open to the household
Income is the payment or the sum of all wages, salaries, earnings, interest obligations, rents received and all the forms of gaining in confirmed time frame.
Prices of other goods and services available.
The price of one good make a difference the price of others. These are goods that substitute or complement one another. The substitute goods are being used as an alternative for others. When the price tag on one good rises, the demand for the other good goes up.
