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.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
