Cassandra is trying to think of a good way to keep her financial records. she makes a lot of purchases, using cash, debit cards, and credit cards about equally. when she gets home every day, she tends to be very tired and doesn’t like to do a lot of organized thinking. she tends to lose individual pieces of paper if she doesn’t file them immediately. what might be a good method for cassandra to use?

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

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
