Step-by-step explanation:

x is the depth. put the given depths in the given formula and then find their difference.

T1=4500/1000=4.5°C

T2=4500/2500=1.8°C

now the difference:

∆T=T2-T1

∆T=1.8-4.5= -2.7°C

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
