If it is known that the income elasticity of demand for the same good is 2.5, estimate the percentage change in demand if consumer income increases from $100 to $300.

500%

Explanation:

Given that,

Income elasticity of demand = 2.5

Consumer income increases from $100 to $300,

Therefore, percentage change in consumer income:

= [($300 - $100) ÷ $100] × 100

=  [$200 ÷ $100] × 100

= 200%

Income elasticity of demand = (% change in Quantity demanded) ÷ (% change in income)

2.5 = (% change in Quantity demanded) ÷ 200%

Hence,

% change in Quantity demanded = 2.5 × 200%

                                                       = 500%

none of these are correct, as they are all sources of american law

a

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
