What is the relationship between the two quantities in the table?
1
2
3
30
60
90
120
The relationship between the quantities is "+ 90."
The relationship between the quantities is "-90."
The relationship between the quantities is "+ 30."
The relationship between the quantities is "x 30."

Step-by-step explanation:

You need 2 columns and 4 rows of data here:

x         y

1           30

2          60

3          90

4         120

Each time x increases by 1, y increases by 30, so the relationship between x and y is y = previous y + 30.  This is the 3rd answer choice.
