[請益] 稅收導致的無謂損失

[Dogss (bi1b1r)]

Daily demand for gasoline at Billy-Bob's Mobile Station is described by Q = 77
6 - 200p, where Q are gallons of gasoline sold and p is the price in dollars.
Billy-Bob's supply is Q = -890 + 1,500p. Suppose the state government places a
 tax of 20 cents on every gallon of gasoline sold. What is the deadweight loss
 resulting from this tax?

有人可以幫忙解答一下嗎 感恩
