Auagaa474 Corporation had sales of $491,300 and average operating assets of $289,000 for the past period. What is the margin that Auagaa474 needed to earn in order to achieve an ROI of 27.2%?

16%

Explanation:

Margin = Net operating income/ Sales

Net operating income is used in the ROI formula;

ROI = Net operating income/ Average operating assets

27.2% = Net operating income / 289,000

Net operating income = 289,000 * 27.2%

= $78,608

Margin = 78,608/491,300

= 16%

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
