Example 1: Cost price of a book is $45 and the selling price is $60.Calculate the profit percentage.
Given that, selling price =$60
Cost price =$45
Profit =selling price –cost price
Profit percentage = (15/45) *100
Answer is 33.33% of profit.
Example 2: Cost price of an item is $90 and the selling price is $120.Calculuate the profit
Selling price =$120
Cost price =$90
Profit = selling price – cost price
= $120 -$90
Profit percentage = (30/90) *100
= 0.3 * 100
= 30 %.

Your tutor has been such an inspiration to me as I have difficulty getting some of the physics concepts down and truly understanding them. She takes the time to fully explain each and every aspect of any problem I might ask for help and always with encouragement and humor.
