The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c

The selling price of an item is $650 marked up from the wholesale cost of $450. Find the percent markup from wholesale cost to s

Blababa [14]

Answer:

The markup percentage is 30.76 %

Step-by-step explanation:

Given as :

The selling price of an item = s.p = $650

The wholesale price of an item = w.p = $ 450

Let The markup percentage = d %

Now, According to question

d % = $\dfrac{\textrm selling price - \textrm whole sell price}{\textrm whole sell price}$

Or, d = $\dfrac{\textrm s.p - \textrm w.p}{\textrm w.p}$ × 100

Or, d = $(\frac{650-450}{450})\times 100$

Or, d = $\frac{200}{650}$ × 100

Or, d = 30.7 5

The markup percentage = d = 30.76 %

Hence The markup percentage is 30.76 % Answer
