What was the net percentage change in the number of employees from the start of 2015 to the end of 2018?
Answer: C
We need to find the number of employees at the end of 2018.
Start of 2015 = 500.
End of 2017 = 620 (from previous question).
Start of 2018 = 620. End of 2018 = 620 + 200 - 100 = 720.
Initial number = 500. Final number = 720.
Increase = 720 - 500 = 220.
Percentage change = \(\frac{220}{500} \times 100 = 220 / 5 = 44\)%.
