Copy Whiz 240 8

Respuesta :

Answer:

Machine Able Copy

Explanation:

The computation is shown below:

Utilization rate = (Mean-time Between Failures) ÷ (Mean-time Between Failures + Mean time to repair)

For Able copy, it would be

= (40 hours) ÷ (40 hours + 1 hours)

= (40 hours) ÷ (41 hours)

= 97.56%

For Business mate, it would be

= (80 hours) ÷ (80 hours + 4 hours)

= (80 hours) ÷ (84 hours)

= 95.24%

For copy whiz, it would be

= (240 hours) ÷ (240 hours + 8 hours)

= (240 hours) ÷ (248 hours)

= 96.77%

As we see the highest utilization rate is of Machine able copy. Therefore, this machine should be purchased.
