Answer:
$3.10
Explanation:
To calculate the profit the store owner makes on a bottle of spices that Jayden buys, we need to consider the cost price, the selling price, and the discount applied. Let's break it down step by step:
Cost price: The store owner buys the bottle of spices for $5.
Markup: The store owner adds an 80% markup to the cost price to determine the selling price.
Markup = 80/100 * $5
= $4
Selling price = Cost price + Markup
= $5 + $4
= $9
Discount: Jayden uses a 10% off coupon to buy the bottle of spices.
Discount = 10/100 * $9
= $0.9
Amount paid by Jayden = Selling price - Discount
= $9 - $0.9
= $8.10
Profit: To calculate the profit, we subtract the cost price from the amount paid by Jayden.
Profit = Amount paid by Jayden - Cost price
= $8.10 - $5
= $3.10
Therefore, the store owner makes a profit of $3.10 on a bottle of spices that Jayden buys.
