    Given that the total profit is determined using the equation:

    P=7.5n - (2.25n+15)

    The minimum cost of necklace will be found as follows:

    writing the above is straight line form of y=mx+c, where m is the slope and c is the y-intercept we get

    P=7.5n-2.25n-15

    P=5.25n-15

    thus the slope is 5.25

    the y-intercept is at (0,-15)

    the minimum amount is 15

    Answer: C. $15
