On a public transportation map to stations are 15 cm apart where is a real life the distance between them is 18 km what is the map scale

there are 100 cm in 1 meter, and there are 1000 meters in 1 Kilometer.

so in 18 Kilometers there are 18*1000 meters, and there are 18*1000*100 centimeters.

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
