What is the store paid $75 for a clarinet and sold it for $100 did the store mark up the price by 30% what the answer

nevsk [136]

Answer:

Mark up = 33.33%

Step-by-step explanation:

Given that:

buying price = $75

selling price = $100

First we will find the difference between two prices:

Difference = 100 - 75 = $25

We will find now that 25 is what percent of 75 so:

=25/75* 100

= 0.333333 * 100

= 33.33%

So the store marked the price by 33.33% instead of 30%

i hope it will help you!

: 11 = 1 /3 : 6<br><br> plz help

GenaCL600 [577]

<h3>Let the number be x</h3>

$x:11 = \frac{1}{3} :6$

Divide the numbers

$\frac{x}{11} = \frac{ \frac{1}{3} }{6} \\ \frac{x}{11} = \frac{1}{18}$

Multiply all terms by the same value to eliminate fraction denominators

$11 \times \frac{x}{11} = 11 \times \frac{1}{18}$

Cancel multiplied terms that are in the denominator

$x = 11 \times \frac{1}{18}$

Multiply the numbers

$x = \frac{11}{18}$
