You need to find out 0,5$ is what pourcentage of 2$
So you need to do a cross product :
0,5 → 2
× → 100
(0,5 × 100) ÷ 2 → 50 ÷ 2 = 25%
So the answer is : The percent markup that is being charged is 25%!
Another way to see it is :
There is 4 times 0,5$ in 2$
So if you take 1/4 of 2$ it’s the same thing as saying that you’re taking 0,5$.
And 1/4 = 25% :)!

You have
y as an implicit function of
x:
sin(xy) – x = 0Use implicit differentiation. As
y is a function of
x, then you must apply the chain rule there:
d d—— [ sin(xy) – x ] = —— (0) dx dx d d d—— [ sin(xy) ] – —— (x) = —— (0) dx dx dx d—— [ sin(xy) ] – 1 = 0 dx d—— [ sin(xy) ] = 1 dx dcos(xy) · —— (xy) = 1 dxNow, apply the product rule for that last derivative:
dyIsolate
—— :
dx dyx cos(xy) · —— = 1 – y cos(xy) dxAssuming
x cos(xy) ≠ 0,
dy 1 – y cos(xy)—— = ———————— <——— this is the answer.
dx x cos (xy)I hope this helps. =)
