C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...

= 8×100% = 800%
Answer:
Length is 10
Width is 8
Step-by-step explanation:
The formula for the perimeter of a rectangle is:
We are told that the length l is 2 more than twice the width w. In other words:
Also, we are given that the perimeter is 28. Therefore:

Divide by 6:
So, the width is 4.
And the length is 2 more than twice the width. Thus:
The length is 10.
And we are done :)
Answer:
Step-by-step explanation:
2(4x - 8) - 10
8x - 16 - 10
|_______|
8x - 26
-5x + 8 - 11x - 12
___ ___ _____ ____
___ ____
-16x - 4
-3(4x - 5)
-12x + 15
For the third and first exercises, you just use the Distributive Property, and for the second exercise, all you are doing is combining like-terms.
