At the school carnival, the sixth graders are making directional arrows, as shown below.

each arrow is to be painted red. how much area needs to be painted for 1 arrow?

a. 26 sq in
b. 29 sq in
c. 32 sq in
d. 38 sq in

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
