Find the difference between the selling price and the cost price, and then express it as a percentage of the cost price.
The selling price for each bottle is £0.50, so the total selling price for 16 bottles is:
The cost price for the 16 bottles is £7.36.
To find the profit, we subtract the cost price from the selling price:
To find the percentage profit, we divide the profit (£0.64) by the cost price (£7.36) and multiply by 100:
- (£0.64/£7.36) × 100 = 8.70%
Therefore, Angelina's percentage profit is 8.70%.
