1. Stating the problem: We need to find the markup price and the selling price per box of mango bars given the original price and the markup percentage. 2. Given data: - Original price per box = 150 - Markup percentage = 12% = 0.12 3. Calculate the markup price using the formula: $$\text{Markup price} = \text{Original price} \times \text{Markup percentage}$$ $$\text{Markup price} = 150 \times 0.12 = 18$$ 4. Calculate the selling price by adding the markup price to the original price: $$\text{Selling price} = \text{Original price} + \text{Markup price}$$ $$\text{Selling price} = 150 + 18 = 168$$ 5. Final answers: - Markup price per box = 18 - Selling price per box = 168
