Answer:
a) To calculate the percent markup, we need to divide the profit by the original cost and multiply by 100 to express it as a percentage:
Markup = (Selling price - Cost) / Cost * 100
Markup = (8.50 - 5) / 5 * 100 = 70%
So the markup on the item was 70%.
b) To find the total profit, we need to subtract the original cost from the selling price:
Profit = Selling price - Cost
Profit = 8.50 - 5 = 3.50
So the total profit on the item was $3.50.
