Answer:
could you provide the equation for which x is to be solved?:)...If your question was supposed to be that ...then hope the solution helps:)
The sample % of these two populations would be 100/size (of student body at each school) x 100 so this would compare the two student bodies preferences for the particular type of candy bar. However, the actual % of the whole student body at each school would be a factor also. If the high school only had 200 students then this would be 50% representative but if the middle school had say 500 students this would only be 20% representative so this would have to be taken into account too. It might be more representative to have the same % of the student bodies respectively for the sample.
3/4. 4/8= 2/4. so 1/4+2/4=3/4
