11.56%
Step-by-step explanation:
The computation of the minimum required rate of return is shown below:
Residual income = Net operating income - (Average operating assets × minimum required rate of return)
$22,000 = $59,000 - ($320,000 × minimum required rate of return)
After solving this the minimum required rate of return is 11.56%
By applying the above formula we can find out the minimum required rate of return
