The management of Mid-Atlantic Railroad Company introduced in Exercise 20-20 improved the profitability of the Boston/Philadelphia route in June by reducing the price of a railcar from $ 614 to 556. This price reduction increased the demand for rail services. Thus, the number of railcar increased by 236 railcars to a total of 768 railcars. This was accomplished by increasing the size of each train but not the number the trains. Thus, the number of train-miles was unchanged. All the activity rats remained unchanged.

(a) Prepare a contribution margin report for the Boston/Philadelphia route for June. Calculate the contribution margin ratio in percentage terms to one decimal place.

(b) Prepare a contribution margin analysis to evaluate management’s actions in June. Assume that the June planned quantity, price, and unit cost was the same as May.
