Assume the following information:

Actual run time this week	4,500	minutes
Machine time available this week	5,000	minutes
Actual run rate this week	3.6	units per minute
Ideal run rate	4.0	units per minute
Defect-free output this week	15,000	units
Total output this week (including defects)	16,200	units

1) The efficiency rate is closest to:

2) The quality rate is closest to:

3) What is the quality loss in units?
