6) The quantity demanded of a certain brand of smart phone is 2000 per week when the unit price is $84. For each decrease in the unit price $5 below $84, the quantity demanded increases by 50 units. The supplier will not market any of the smartphones if the unit price is $60 or less, but the supplier will market 1800 per week if the unit price is $90. The supply and demand equations are known to be lineara) Find the demand and supply equationsb) Find the equilibrium quantity and price
only typed answer
A consumer has inverse demand of
p=15−1q
for a good and the market price is
$4.00.
Calculate consumer surplus and the total value of the good for the corresponding quantity consumed.
Consumer surplus is $enter your response here.
(Enter your response rounded to two decimal places.)
The consumer's expenditure for the good is
$enter your response here. (Enter your response rounded to two decimal places.)
