Answer:
The profit margin will need to be of 7.57%
Explanation:
the profit margin is the ratio between net income and sales
net income / sales = profit margin
We are asked for the profit margin at which ROE = 15%
ROE return on equity
ROE = net income/ equity
This company has zero debt, so equity = assets = 312,900
Desired ROE = 15%
net income / equity = 15%
net income / 312,900 = 15%
312,900 x 15% = net income
target net income = 46,935
target profit margin
target net income/ sales
46,935/620,000 = 0,07570161 = 7.57%
