Answer:
deadwweight loss $2,250
Explanation:
The deadweight loss is the area loss between the new consumer and producer surplus after-taxes and the previous consumer and prodcuer surplus after taxes
As this is a straight line then we have the area of a triangle which height is
P2 - P1 in this case the $15 tax levied
and Q2 - Q1 as the high of the triangle in this case 300 units
We now sovle for the area of the triangle:
300 x 15 / 2 = 2,250
