Answer: Hi your question is incomplete attached below are the missing details
answer :
A) 16 used DVDs
B) i) $18
ii) $6
iii) $8
Explanation:
A) Determine the weekly shortage of used DVDs due to ceiling price = $11
shortage = Quantity demanded ( H ) - Quantity supplied ( F )
at ceiling price of $11 ; quantity demanded = 20 , Quantity supplied = 4
= 20 - 4 = 16 used DVDs
B) i) New consumer surplus = ADLK
ADLK = ∠ ABK + BKLD
= 1/2 * 4 * 1 ) + ( 15 - 11 )*4 = $18
ii) New producer surplus = DLE
DLE = 1/2 * 4 * ( 11-8 )
= $6
iii) Total economic surplus lost
ΔKJL = 1/2 ( 8 - 4 ) * ( 15 - 11 )
= $8
