An electronics company makes communications devices for military contracts. The company just completed two contracts. The navy contract was for 2,540 devices and took 27 workers two weeks (40 hours per week) to complete. The army contract was for 5,940 devices that were produced by 37 workers in three weeks (40 hours per week). a. Calculate the productivity for navy and army contracts in units produced per labor hour.

Explanation:

For Navy contract, the total number of man hours put into production will be:

= 27 × 40 × 2

= 2160 man hours

Then, the units produced per labor hour will be:

= 2540 devices / 2160

= 1.176 units per labor hour.

For Army contracts, the total number of man hours put into production will be:

= 37 × 40 × 3

= 4440 man hours

Then, the units produced per labor hour will be:

= 5940/4440

= 1.338 units per labor hour.
