The supply curve for aluminum is estimated to? be: Q = 0.1p such that \eta = 1a) The? pre-tax equilibrium price is: 66.66b) The? pre-tax equilibrium quantity is: 6.66c) If a $40 tax per pound is placed on? aluminum, the price paid by consumers would be: $80d) And the new equilibrium quantity sold is: ? (rounded to two decimal places)
