The length of a rectangle is 3 units more than the width. The area of the rectangle is
54 units. What is the width, in units, of the rectangle?

  6 units

Step-by-step explanation:

Since you're familiar with your times tables, you know that 6×9 = 54. Since the area is the product of length and width, these numbers could be the length and width of the rectangle.

We notice that 9 is 3 more than 6, so corresponds to the requirement for length. Then the width of the rectangle is 6 units.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
