Answer:

$2.35 for one video

Step-by-step explanation:

You set up two equations:

$7.50= p + 2v

$12.20= p + 4v

You then set both equal to p

p=-4v+12.20 and p=-2v+7.50

So you can set them equal to each other and solve for v (the cost of one video)

v= $2.35

$\frac{dy}{dx}$ = - $\frac{9}{8x^{4} }$

let y = $\frac{3}{(2x)^{3} }$ = $\frac{3}{8}$ $x^{-3}$

differentiate using the power rule

$\frac{d}{dx}$ ( $ax^{n}$ ) = na $x^{n-1}$

$\frac{dy}{dx}$ = - $\frac{9}{8}$ $x^{-4}$ = - $\frac{9}{8x^{4} }$
