How do you find the percentage off?

Answer 1

to find a percentage of something you can divide it by 100 and times by the percentage you want e.g.

48% of 100 is 100 divided by 100 = 1 times by 48 is obiously 48

to find percentage change it is current number divided by original times by 100% then subtract 100%. So if a store's sales were $50000 one month, then the next month $60000, the percentage change is (60000/50000 x 100% ) - 100% = (1.2 x 100%) - 100% = 120% - 100% = +20% change. If the values decrease, then the percentage change will be negative.

So if a store has a sale with 30% off, this is a -30% change. To calculate the new price with the discount: Take 100% minus (discount percentage) then multiply this (as a decimal) by the original price. So for 30% discount on a $20 item: 100% - 30% = 70%, which is 0.70 as a decimal. Multiply 0.70 x $20 = $14. The new price with a 30% discount is $14.
