The formula for calculating the mark up percentage is as follows:
sticker price - invoice price/invoice price • 100 = percent mark up
<h3>How to find the percentage mark up?</h3>
Percentage mark up can be described as follows:
percentage mark up = selling price per unit - cost price per unit / cost price per unit × 100
Therefore,
Mark up is the difference between a product's selling price and cost as a percentage of the cost.
Therefore, the formula for calculating the mark up percentage is as follows:
sticker price - invoice price/invoice price • 100 = percent mark up

Answer:
A
5(15x-4)^3
Explanation:
I assume you mean g(f(h(x))) so in that case here is how you do it:
So the first one is g(x) which is:
5x^3
Now g(f(x)) you just plug in f(x) for the x in the g equation. It would look like this:
5(5x-4)^3
Now the h(x) you would do the same, plug it in for all the values of x in g(x). So it would look like this:
5(5(3x)-4)^3
Since you simplify, you get 5(15x-4)^3
This final equation is g(f(h(x))) which is what you were looking for, which is A
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.
28 times 7.5 (30 divided by 4) = 210 :)
