Answer:
$30
Step-by-step explanation:
Mark up is the profit on cost. if the pair of jeans was $45 after a 50% markup
Let the price of the jeans before the markup be p then;
p + 50%p = 45
1.5p =45
p = 45/1.5
p = 30
The price before mark up was $30, while the mark up or profit is $15. This shows 50% of the price before mark up.
