Answer :
The mark-up in percentage is 76%.
Step-by-step explanation:
The given information are,
The manager of a store orders cell phones that costs $25.
Therefore, the cost price of the cell phone = $25
He sells them at the cost of $44.
Therefore, the selling price of the cell phone = $44.
To find the profit the manager makes by selling the cell phone is calculated by the formula :
Profit = Cost price - selling price.
Profit = 44-25 ⇒ 19 dollars.
The difference between cost price and selling price is $19.
To find the percentage increase (mark-up value) :
Marked up = (Profit / cost price) × 100
⇒ (19/25) × 100
⇒ 76%
Therefore, the mark-up in percentage is 76%.
