Provide detail solution with working notes.....Springfield Express is a luxury passenger carrier in Texas. All seats are first class, and the following data are available:

Number of seats per passenger train car 90

Average load factor (percentage of seats filled) 70%

Average full passenger fare $ 160

Average variable cost per passenger $ 70

Fixed operating cost per month $3,150,000

a. What is the break-even point in passengers and revenues per month?

b. What is the break-even point in number of passenger train cars per month?

c. If Springfield Express raises its average passenger fare to $ 190, it is estimated that the average load factor will decrease to 60 percent. What will be the monthly break-even point in number of passenger cars?

d. (Refer to original data.) Fuel cost is a significant variable cost to any railway. If crude oil increases by $ 20 per barrel, it is estimated that variable cost per passenger will rise to $ 90. What will be the new break-even point in passengers and in number of passenger train cars?

e. Springfield Express has experienced an increase in variable cost per passenger to $ 85 and an increase in total fixed cost to $ 3,600,000. The company has decided to raise the average fare to $ 205. If the tax rate is 30 percent, how many passengers per month are needed to generate an after-tax profit of $ 750,000?

f. (Use original data). Springfield Express is considering offering a discounted fare of $ 120, which the company believes would increase the load factor to 80 percent. Only the additional seats would be sold at the discounted fare. Additional monthly advertising cost would be $ 180,000. How much pre-tax income would the discounted fare provide Springfield Express if the company has 50 passenger train cars per day, 30 days per month?

g. Springfield Express has an opportunity to obtain a new route that would be traveled 20 times per month. The company believes it can sell seats at $ 175 on the route, but the load factor would be only 60 percent. Fixed cost would increase by $ 250,000 per month for additional personnel, additional passenger train cars, maintenance, and so on. Variable cost per passenger would remain at $ 70.
