Answer: [tex]New supply equation = Qs= 4P - 36[/tex]
Explanation: A supply equation shows us the mathematical relationship between quantity supplied and the price of the good. Since price and supply are positively related, P must carry a positive sign in the supply equation.
Given, supply is Qs=4P - 24
P is the price paid by consumers in the market.
When a $3 tax is levied , price sellers receive becomes P-T = P - 3
So, the new supply equation will be
[tex]Qs= 4 (P-3) - 24
Qs= 4P - 12 - 24
Qs= 4P - 36[/tex]
