Please help me in answering some questions below. For question #1, please show the solution. Thank you so much.

Question 1: To help airport security, Canada imposed the Air Travelers Security Charge (ATSC), an excise tax on the sale of domestic airline tickets. In 2017, the total excise tax was S 14.96 per roundtrip domestic airline ticket. According to Stats Canada, 67.8 mm passengers travelled on one-way domestic airline trips in 2017, with an average price of 5 248.60. The following table shows the supply and demand schedules for airline trips. The quantity demanded at the average price ofS 248.60 is actual data; the rest is hypothetical. Price of Trip Quantity of trips Quantity of trips demanded (millions) supplied (millions) S 250.00 66.0 82.4 5 248.60 67.8 77.6 5 241.60 73.8 73.8 5 233.64 ' 80.8 67.8 S 233.00 85.3 66.0 a) What is the revenue in 2017 from the excise tax? b) What is the approximate loss of welfare or dead weight loss associated with the excise tax? c) Suppose on January 1, 2018 the total excise tax will increase to 5 17.00 per ticket. Assume the supply and demand schedule does not change. What is the quantity of tickets transacted now? What is the price for tickets now? What will be the dead weight loss? What will be the tax revenue in 2018 for the ATSC tax? Does this increase in the excise tax increase or reduce the revenue of ATSC? Question 2: In 2017, the Trump administration enacted a significant tax reform which lowered taxes for individuals and corporations. In fact, it was the largest corporate tax cut in US history. Trump and his administration argued that government would raise more tax revenue by reducing the marginal tax rates. Why were (and are) most economists skeptical about this argument
