an ACTUALLY helpful and fast guide for when something is on sale and you don’t have a piece of paper bc who tf brings a piece of paper when you’re shopping: a THREAD (i guess)

the percent of the price that is on the tag is always 100%, now if it is 60% off then it means the item is going to cost 40% because 100% - 60% = 40%.

now 100% of the price equals to 1.00, IF we use this method then 60% = .60 and 40% = .40. WITH THIS INFORMATION you type your price on your calculator app and multiply by .40 and that’s the price you’re going to pay, TAX NOT INCLUDED. example using $16.99 as a price (video):

now the price with discount has become your 100% = 1.00, IF YOU WISH TO KNOW YOUR PRICE WITH TAX multiply your new price by 1.09 (using chula vista, ca. tax rate) which is 8.75% = 0.0875 but it’s easier to round it to the next number. like so:

this has helped me a lot, i’m someone who needs to have things explained detail by detail. i hope it’s not tedious and that you understand. i’m no expert but my mom is an accountant and she approves my method. thx. end of thread i guess.

ps. idk if i used the right terminology bc i’m not an expert i hope i don’t cause any confusion.
