I have a little trouble understanding this, please help. Penelope buys bracelets in bulk at a cost of 8$ each to sell at her store. She uses a markup rate of 125%, which is added to the bracelet cost. What is the retail price of the bracelet?
I only need a equation which goes by y=x and y=, markup amount, and the final retail price which is the cost+markup+=retail price. Thank you ☺️

breadth = 3 unit

applying the formula,

= 10 × 3

= 30 unit^2
