Answer:

Option C, 6.5

Step-by-step explanation:

<u>Step 1:  Substitute y in the equation 3x - 5y = 22</u>

3x - 5y = 22

3x - 5(-5x + 32) = 22

3x + 25x - 160 + 160 = 22 + 160

28x / 28 = 182 / 28

x = 6.5

Candy Crunchers wants to see if their new candy is enjoyed more by high school or middle school students. They decide to visit o
umka21 [38]
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.
