A merchant buys a television for $125 and sells it for $75 more. what is the percent of markup?
guajiro [1.7K]
Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price   * 100%

% Mark Up =   75 / 125 * 100%
            
                   =   0.6  * 100% = 60%

Percent Mark Up = 60%.

kumpel [21]

Answer:

Step-by-step explanation:

3x and 3y are not "like terms," despite having the same coefficient.

Find the volume of a cube with side length of 7 in.
anastassius [24]

Answer: 343 in³

Explanation: In this problem, we're asked to find the volume of a cube.

It's important to understand that a cube is a type of rectangular prism and the formula for the volume of a rectangular prism is shown below.

<em>Volume = length × width × height</em>

In a cube however, the length, width, and height are all the same. So we can use the formula side × side × side instead.

So the formula for the volume of a cube is side × side × side or s³.

So to find the volume of the given cube, since each side has a length of 7 inches, we can plug this information into the formula to get (7 in.)³ or (7 in.)(7 in.)(7 in).

7 x 7 is 49 and 49 x 7 is 343.

So we have 343 in³.

So the volume of the given cube is 343 in³.
