PLEASE EXPLAIN STEP BY STEP :)

An analyst compiles the following data for a company:

	FY13	FY14	FY15
ROE	19.8%	20.0%	22.0%
Return on total assets	8.1%	8.0%	7.9%
Total asset turnover	2.0	2.0	2.1

Based only on the information above, the most appropriate conclusion is that, over the period FY13 to FY15, the company's:

	net profit margin and financial leverage have decreased.
	net profit margin and financial leverage have increased.
	net profit margin has decreased but its financial leverage has increased.
