Question 220726: This is a word problem my son just had on a quiz and I couldn't solve either. I thought we didn't have enough info.
Marshfield Middle school cluster C has 100 students in honors pre-algebra
Cluster C has 30 students enrolled in after school math enrichment.
If 105 cluster C students are in only one or the other of these, how many students are in both?
Tried a venn diagram to get my mind around it, didn't work. (I keep thinking I need to know the total enrollment of honors pre-alg plus after school)my son said he got 12.5 as an answer, but the teacher said it would come out as a whole number.
Thanks, Trish
