Answer: 7.2 printers
Step-by-step explanation:
From the question, we are informed that a standard worker produces 8 printers per one shift and that the work average is such that 90% efficiency is expected.
The actual number of printers that should be produced per one shift would be gotten by multiplying the efficiency by the standard worker output. This will be:
= 8 × 90%
= 8 × 90/100
= 8 × 0.9
= 7.2 printers
