Answer:
51.8% and 44.21%
Explanation:
The computation is shown below:
Initial markup = (Original price - initial price) ÷ (Original price)
= ($1,100 - $530) ÷ ($1,100)
= $570 ÷ $1,100
= 51.8%
And, the maintained markup is
= (Sale price - cost price) ÷ (Sale price)
= ($950 - $530) ÷ ($950)
= $420 ÷ $950
= 44.21%
The markup always expressed in percentage forms
