Answer:
$49,200
Step-by-step explanation:
The turnover hinted in the question means asset turnover, which can be used to determine the worth of assets invested in the year as follows:
asset turnover=net sales/total assets
assets turnover=2.8
net sales=$410,000
total assets employed in the year is the unknown
2.8=$410,000/total assets
2.8*total assets=$410,000
total assets=$410,000/2.8= $146,429
return on investment=net operating income/total assets
return on investment=33.6%
net operating income is unknown
total assets=$146,429
33.6%=net operating income/$146,429
net operating income=33.6%*$146,429 =$49,200
