i need help to solve this 2 part question for algebra, and could y’all possibly explain the steps after giving the answer ?

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

what is the original number? you forgot to add it.

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
