Answer:
Step-by-step explanation:
The given expression is
Now, to find the expression for , we just have to isolate it. First, we have to move the term
to the other side of the equation, and then to move the coefficient
, which is gonna pass to the other side dividing.
Therefore, the percent markup is defined as the difference between the selling price and cost, divided by that cost.

<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
Thus:
Therefore, the equation of the sinusoid is:
Answer: C
