Answer:
Option (A).
Step-by-step explanation:
It has been given in the question,
Function that defines the number of headbands Ms Roth can sell is,
N(p) = 200 - 1.5p
Here 'N(p)' denotes the number of headbands sold and p denotes the price of one band.
Therefore, Total sales of the band = price of one band × Number of bands sold
If we represent the total sales by S(p), then the function defining the total sales will be,
S(p) = p. N(p)
S(p) = p.(200 - 1.5p)
Option (A) will be the answer.
