Halpert Corporation has been in operation for one year. The only product they produce is a specific bicycle chain. They want to make sure they are effectively utilizing the machinery they use to create this product. Below is the information concerning the machine that produces the bicycle chain: Halpert's utilization rate for the week was:

A) 0.42
B) 0.75
C) 0.80
D) 0.85

To calculate utilization rate, we use the formula:

Utilization rate = Actual output / Maximum possible output

From the given information, the machine produces one bicycle chain every 4 minutes. In a 40 hour week (assuming a 5-day work week), there are 2400 minutes available (40 hours x 60 minutes per hour).

Therefore, maximum possible output = 2400 / 4 = 600

If Halpert Corporation produced 480 bicycle chains during the week, then the actual output for the week is 480.

Utilization rate = 480/600 = 0.80

Therefore, the answer is C (0.80).
