ticket sales the school sold 4 adult tickets
and 6 child tickets for a total of $80. The
school took in $84 on the second day by
selling 4 adult tickets and 7 child tickets.
Find the price of an adult ticket and the
price of a child ticket.

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
