If there are exactly 5 times as many children as adults at a show, which of the following cannot be the number of people at the show?
a) 102
b) 80
c) 36
d) 30

If the number of adults in  the show would be represented by the variable a, the relationship of the number of adults and the children will be:

a=5a

therefore, the number of people in the show would be represented by:

5a+a or 6a

Therefore, 80 cannot be the number of people in the show because it is not divisible by 6
