Answer:

d. 192

Step-by-step explanation:

OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:




0.7(total 8th graders) = 112


total 8th graders = 112/0.7


total 8th graders = 160




And since the number of 8th graders is 5/6 the size of the 7th grade class:


5/6(7th grade class) = 160


5(7th grade class) = 960


7th grade class = 192.




The correct answer is D) 192.
