The question is not clear here for me plz put the graph so I may answer
4 and 1 over 2 times 2 and 3 over 2
(this shows the percent of people that would work over time on a regular basis out of the 30 people) 12/30= (40%) of the 30 said they would work overtime.
200×.4=80 employees of the 200 would have probably have said they would work overtime.
