For which student do the hours worked and wages earned represent a PROPORTIONAL relationship?

Answer 1

B $6 $12 $18 $24 $30 $36 $42 $48

Explanation:

6 The relationship is 6

6+6=12

12+6=18

18+6=24

24+6=30

30+6=36

36+6=42

42+6=48

Answer 2

The quickest way to figure this out is to think which numbers are multiples of the first number. 7 to 12 is not a 7 dollar difference so no. 6 to 12 is 6 so yes. 12 to 18 is 6 so yes. 18 to 24 is 6 so yes. Now to the next, 5 to 5 is not a 5 difference, so no. 1 to 4 is not a 1 difference so it's wrong. The only one that is right is student b.
