andrew11 [14]
Hello!

First you find how far he went

So he we 96 kilometers there and back

96 + 96 = 192

It took him 8 hours to go 192 kilometers

To find the average speed you divide these two

192/8 = 24

So his average speed was 24 kilometers an hour

The answer is 24

Find the selling price of a $20 item after a 20% markup.
nevsk [136]

Answer:

$24

Step-by-step explanation:

For a markup, use the formula <em>a = ( 1 + p ) × w. </em>

!!! Remember, <em>a </em>is the selling price, and <em>w </em>is the original price !!!

!!! The <em>p </em>is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!

<em />

Inserting the values, it should look like <em>a = ( 1 + 0.20 ) × 20 </em>

<em>a = 1.20 × 20 </em>

<em>a = 24</em>

<em />

Hence, the new selling price is $24.

Hope this helps! :)
