Answer: $609.70
Explanation:
Given : A clerk is marking up merchandise 34%.
The original price of an item is $455.
Then, the Mark up price = 34% of Original price
⇒ Mark up price
[Replace 'of' by '× 'and convert percentage into decimal by dividing it by 100 ]
⇒ Mark up price= $154.70
Now , Retail price = Original price + mark up price
= $455+$154.70 =$609.70
Therefore , the retail price will be $609.70 .
