Step-by-step explanation:
Calculation for overhead application rate

Total Direct Labor Cost = 60,000 hours * $10/hr Total Direct Labor Cost= $600,000
Last step is to calculate Overhead application rate
Overhead application rate = $900,000/$600,000
Overhead application rate = 1.5*100
Overhead application rate=150%
Therefore Cosi Company's overhead application rate is 150%
