Great video thanks really. Sometimes I get my formula correct but my answer is wrong because I don't pay attention to what I'm doing!

Easiest way to calculate your sales tax is to add the tax rate for you purchase. for example if your purchase is 49.99 and the tax rate is 8% or 8.85%. 49.99+8%=53.98. 49.99+8.85%=54.41 and if you need the actual number of the tax, you have to subtract your non taxed total from your taxed total. Example 54.41 - 49.99 =4.42 or 53.98 -49.99 = 3.99

thank you so much dude <3
this was some great advice.

lets say you already know the sales tax of a certain store, and you want to know how much you would be paying for an item plus tax ahead of time. well, what if the sales tax is already in decimal form such as 8.75%. my main question is, it is already in decimal form but yet, it is a percentage. do you have to change anything, or do you move it 2 places to the left from the existing period??!?! (please reply)

tax in canada is so expensive its 13% !

[carlantonbien]

Good day sir, I have a question where did you get the 1.07 to multiply the $249.99? Because I don’t understand, Please enlighten me

[BossChronicles]

What major teaches you these topics ?

[KurruptLyfe]

That's what he was talking about @ 1:32. You have to round off the second number to the right of the decimal. You got 17.499, right? So because the third number to the right (being 9) is higher than 5, that changes the 49 to 50.

[tarynnnnn]

It will just be let's say 24.99 is your price, you just do 24.99 times 5.25 .

its easier just adding the tax to the price than  multiplying 1.07...
