Beginning from a depth of 35 feet below the surface, a whale swims
upward and jumps to a height of nearly 17 feet above the surface.
a. model with math use an inequality to model the possible change in the number of feet, r, of the whale's elevation.
b. solve the inequality. explain the meaning in terms of the situation.

-2 is the right

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
