Marketing Problems and answers

1.) Suppose that in 2010, Global launches an aggressive marketing campaign that boosts sales by 15%. However, their operating margin falls from 5.57% to 4.50%. Suppose that they have no other income, interest expenses are unchanged, and taxes are the same percentage of pretax income as in 2009.


  • What is Global’s EBIT in 2010?

Ans: Let us assume the Net Sales in 2009 to be Y

Operating Margin = Operating Income / Net sales.

Operating Income = Operating Margin X Net Sales

For 2010

Operating margin is 4.5%

Net sales = Y(1+.15) = 1.15Y

Operating Income = .45 x 1.15Y

This is the Earnings before Interest and Tax (EBIT)
