Answer:
Elastic demand
Unit elastic demand
Inelastic demand
Explanation:
Elasticity of demand measures the degree of responsiveness of quantity demanded to changes in price.
Elasticity of demand = percentage change in quantity demanded/ percentage change in price.
Denand is elastic if when price is increased, the quantity demanded changes more than the increase in price. Quanitity demanded is more sensitive to changes in price.
If price is increased, the quantity demanded falls and as a result the total revenue earned by sellers falls.
The elasticity of demand is usually greater than 1 when demand is elastic.
Demand is unit elastic if a change in price has the same proportional change on quantity demanded. The coefficient of elasticity is equal to one.
If price is increased, the quantity demanded changes by the same proportion so there's no change in total revenue of sellers.
Demand is inelastic if a change in price has little or no effect on quantity demanded.
Coefficient of elasticity is usually less than one.
If price is increased, there is little or no change in the quantity demanded and as a result the revenue earned by sellers increase.

Answer:
Per Chevron 3Q 2013 Filling:
The percentage change in the cost of purchased oil products nine months to September 30, 2013 when compared to nine months in 2012 was:
2.47%
Explanation:
a) Data and Calculations:
Cost of purchased oil products:
2013 $34,822,000,000
2012 $33,982,000,000
Change $840,000,000
Percentage Change = $840/$33,982 x 100
= 2.47%
b) The implication is that Chevron's cost of purchased oil products in third quarter of 2013 increased by 2.47% when compared with the same period in 2012. This percentage change is calculated by subtracting the Q3 2012 cost of purchased oil products from the Q3 2013 cost of purchased oil products and then dividing the difference by the Q3 2012, and multiplying by 100. The change could be caused by increases in the price of oil products or other variables.
