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

Formula :
Revenue = Units Sold * Unit price
Contribution Margin = Revenue – All Variable Cost
Contribution Margin Ratio = Contribution Margin/Selling Price
Break Even Points in Units = (Total Fixed Costs + Target Profit )/Contribution Margin
Break Even Points in Sales = (Total Fixed Costs + Target Profit )/Contribution Margin Ratio
Margin of Safety = Revenue – Break Even Points in Sales
Degree of Operating Leverage = Contribution Margin/Net Income
Net Income = Revenue – Total Variable Cost – Total Fixed Cost
Unit Product Cost using Absorption Cost = (Total Variable Cost + Total Fixed Cost)/# of units

Contribution margin per passenger =?
Contribution margin ratio =?
Break-even point in passengers = Fixed costs/Contribution Margin =
Passengers =?
Break-even point in dollars = Fixed Costs/Contribution Margin Ratio =
$ ?

Compute # of seats per train car (remember load factor?)
If you know # of BE passengers for one train car and the grand total of passengers, you can compute # of train cars (rounded) =?

Contribution margin =?
Break-even point in passengers = fixed costs/ contribution margin
Passengers =?
train cars (rounded) =?

Contribution margin =?
Break-even point in passengers = fixed costs/contribution margin
Passengers =?
train cars ( rounded) = ?

Before tax profit less the tax rate times the before tax profit = after-tax income = $ ?
Then, proceed to compute # of passengers -=?

# of discounted seats = ?
Contribution margin for discounted fares X # discounted seats = $ each train X$ ? train cars per day X ? days per month= $? minus $ additional fixed costs = $? pretax income.

1.

Compute Contribution margin

Then,

# seats X $ X # train cars = $ ?
Increased fixed cost ( ?)
Pretax gain (loss) on new route $

2 and 3. Compute # of passengers and train cars using computation approaches employed in some of the above problems.
