Answer: See explanation
Explanation:
a. Calculate the productivity for navy and army contracts in units produced per labor hour.
Based on the information given, for the navy contract, the total man hours to make 3380 devices will be:
= 34 × 40 × 2
= 2720 hours
Therefore, the devices per man hour will be:
= 3380/2720
= 1.24 devices per labor hour.
For the army contract, the total man hours to make 7480 devices will be:
= 44 × 40 × 2
= 3520 hours
Therefore, the devices per labor hour will be:
= 7480/3520
= 2.125 devices per labor hour
b. On which contract were the workers more productive?
The workers were more productive on the Army contract as they produced more devices per labor hour.
