The formula for return on investment =net income/average operating assets*100
For Osaka division:
net income is $749,000

net income is $3,330,000
average operating assets is $18,500,000
return on investment=$3,330,000/$18,500,000
=18%
Even though Yokohama has a higher net operating income ,the Osaka division recorded a better performance using ROI as a performance metric,which shows profit computation is an absolute figure which does not consider the amount of resources invested in order to earn the profit
