Answer:
30$
Explanation:
Mark up is the increase of the cost for an item. if the pair of jeans was $45 after a 50% markup , let the price of the jeans before the markup be represented by p.
p + 50%p = 45
1.5p =45
p = 45/1.5
p = 30
The price before mark up was $30, while the markup is $15.
50% of $30 = $15.
$30 + $15 = $45
