Answer:
the markup percentage is 66.67%
Step-by-step explanation:
The computation of the percent of markup based on cost is shown below:
= (Selling price - paid price) ÷ (paid price)
= ($15 - $9) ÷ ($9)
= 66.67%
By taking the difference of the selling price & paid price and then divided it by paid price we can get the percentage of markup
Hence, the markup percentage is 66.67%

Answer:
The exact answer is sqrt(170)
The approximate answer is roughly 13.0384
=======================================
Explanation:
We have a right triangle with two known sides. Use the pythagorean theorem to find the third side
Known sides:
a = 7
b = 11
Unknown side is c which is the hypotenuse (longest side)
a^2 + b^2 = c^2
7^2 + 11^2 = c^2
49 + 121 = c^2
170 = c^2
c^2 = 170
c = sqrt(170)
c = 13.0384
Note: the last value is approximate
