Answer:
The selling price of sandals is: $32.77
Step-by-step explanation:
Mark up is the price that is added to the cost price of a product for profit.
Given
Price of sandals = $22.60
Mark up = 45%
To find the price with mark up, we will find the amount of mark up and then add it to the cost price of sandals.

The mark up is $10.17
Now,

Hence,
The selling price of sandals is: $32.77
First, subtract both sides by 8x and you would get:
1 - 11x = 3
Then, subtract both sides by 1 and you will get:
-11x = 2
Divide both sides by -11:
x = -2/11
