Discounts: are the percentage of an item that is removed from the total cost
I'll be determining how much you will pay for;
25% off a $15 shirt
Equation
Percentage × Total Price
Total Price - Previous Answer
Solving the question
0.25 × 15 = 3.75
15 - 3.75 = 11.25
Therefore, today's price for the shirt is $11.25.
Hopefully the formula is correct it was something I learned in math class
