Answer:
$24
Step-by-step explanation:
For a markup, use the formula a = ( 1 + p ) × w.
!!! Remember, a is the selling price, and w is the original price !!!
!!! The p is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!
Inserting the values, it should look like a = ( 1 + 0.20 ) × 20
a = 1.20 × 20
a = 24
Hence, the new selling price is $24.
Hope this helps! :)
