Percentage = (Part / Total) x 100
Example: 45 out of 60 equals (45 / 60) x 100 = 75%.
((New - Original) / Original) x 100
Example: from 80 to 100 is (20 / 80) x 100 = 25% increase.
Price x (1 - Discount / 100)
Example: a $100 item with a 20% discount costs $80.
Amount x (1 + Tax Rate / 100)
Example: $50 plus 8% sales tax totals $54.
Divide the part by the total, then multiply by 100. For example, 25 out of 200 is 12.5%.
15% of 200 is 30, because 200 x 0.15 = 30.
Use ((new value - original value) / original value) x 100. A rise from 50 to 75 is a 50% increase.
Find the discount amount, then subtract it from the original price. A 30% discount on $100 gives a final price of $70.
