After test marketing a new high-fiber cereal, the market research department of a major food producer estimates that monthly sales (in millions of dollars) of cereal will grow at a monthly rate of S'(t) = 1 2 dt, t months after the ( 12 + 1 ) 2 cereal is introduced. If we assume 0 sales at the time the cereal is introduced, show the sales over the first 4 years geometrically, and describe the geometric representation. Which graph geometrically represents total sales? O A. O B. O C. OD.
