Basically the formula is as follows: When figuring tax, you multiply the price of the item, say it's $5, by 1.0725 (the tax here in California is 7.25%, which converted to a decimal is .0725, and the 1 before it is so it will ADD the $5 to the tax amount, instead of just telling you what tax will be). For example: $5 x 0.0725 = $0.36 Therefore: $5 x 1.0725 = $5.36 So since you multiplied to get that answer, you will divide to remove it. Example: 5.36 / 1.0725 = $5 Got it? Just remember to round your numbers up if need be, otherwise you won't get the correct amount. Good luck!

you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.
Well, honey, if your total is $15.45 and you're paying with a $20 bill, you'll get back $4.55 in change. Simple math, no need to overcomplicate things. Just make sure you count your coins before strutting out of that store like you own the place.
The formula is: Number of sides = 6.

Do the maths normally, ignoring the dollar signs. Then just add them in front of the answer at the end.
