The scale factor is 1.25 !

Step-by-step explanation:

Take the sides of one triangle and divide them by the sides of the other triangle.

45/36 = 1.25

30/24 = 1.25

35/28 = 1.25

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
