Answer:
The tax on hearing aid is $120 per unit.
Step-by-step explanation:
The supply curve for hearing aid is a typical upward-sloping straight line, and the demand curve is a typical downward-sloping straight line.
A tax is imposed on each unit of hearing aid.
As a result of the tax, the equilibrium quantity of hearing aids decreases from 10,000 to 9,000.
The deadweight loss of the tax is $60,000.
Deadweight loss =

$60,000 =

$60,000 =

Tax =

Tax = $120
