Respuesta :

Answer:

(a) 0.8013; 0.9926

(b) Army contract

Explanation:

So for the navy contract,

there were a total of 26 × 40 × 3 = 3,120 man hours put in to make 2500 devices.

Devices per man hour:

= 2,500 ÷ 3,120

= 0.8013

For the army contract,

there were a total of 34 × 40 × 4 = 5,440 man hours put in to make 5,400 devices.

Devices per man hour:

= 5,400 ÷ 5,440

= 0.9926

So they were more productive on the army contract.
