Further explanation:
Profit is the money someone earns on selling a product on more than its actual cost.
The formula for profit is:
Given
Purchase price of energy drinks = £9.25
Selling price of one bottle=£1
Selling price of 12 bottles=1*12=£12
Profit= Selling Price - Purchse price
=12-9.25
=£2.75
Brad's profit was £2.75
Now,
Profit percentage= (Profit/Purchase Price)*100
=(2.75/9.25)*100
=0.30*100
=30%
Brad's profit was 30%
