What percentage of the total staff is certified and available to work in the neonatal unit if 35% are unavailable and 20% of the remaining are certified?

A. 7%
B. 13%
C. 65%
D. 80%

The correct answer is: B. 13%

To determine the percentage of the total staff that is certified and available to work in the neonatal unit, we first need to analyze the staff's availability and certification status. Starting with the total staff, if 35% are unavailable, this means that 65% of the staff is available to work. Now, we focus on the available staff. Out of this 65%, it is given that 20% are certified. To find the actual percentage of the total staff that is both certified and available, we take 20% of the 65% that is available. This can be calculated as follows: 1. Calculate the percentage of the total staff that is available: - Available staff = 100% - 35% = 65%. 2. Calculate the certified staff from the available pool: - Certified staff = 20% of available staff = 20% of 65%. To perform this calculation: 20% of 65% = 0.20 × 65 = 13%. Therefore, the percentage of the total staff that is certified and available to work in the neonatal unit is 13%. This aligns with the answer choice selected, confirming its correctness and helping clarify how the percentage was derived.
