Answer:
4,845 cranks
Step-by-step explanation:
Given that
Production per hour = 100 crank
Hours per day = 12
Days per week = 5
Available time = 95%
Achieved efficiency level = 85%
Production per day
= hours per day × production per hour
= 12 × 100
= 1,200 crank
Production per week = Days per week × Production per day
= 5 × 1,200
= 6,000 cranks
Adjusted output of maintenance = Available time × Production per week
= 0.95 × 6,000 cranks
= 5,700 units
Weekly output = Achieved efficiency × Adjusted output of maintenance
= 0.85 × 5,700
= 4,845 cranks
