Answer:
Step-by-step explanation:
Given that a candy bar costing 0.52 is marked up to 0.79 as selling price
Selling price = 0.79
Cost price = 0.52
Difference = 0.27
IF for cost 0.52 the mark up amount is 0.27
Then for 100 mark up amount = 27/0.52=51.92
52%
So there is a mark up of 52% on cost price
Actual mark up is 0.27 dollars
