formula for percentage?

(price) + (tax)(price) = total

Or, (1 + tax)(price) = total

Since tax is given as a percentage, you write it as a decimal by dividing the percentage by 100.

In your case, the tax is 7.75%, or as a fraction, 7.75/100 of the price of the item ==> 0.0775 as a decimal.

(1 + 0.0775)(item price) = 35

price = (35) / (1.0775) = $32.48

Hope that helps ;)

cost = (1 + r ) price

where r is the tax rate as a decimal and price is what the original price is before the tax and cost is the cost that you must pay.

35 = ( 1 + 0.0775 ) p and now you must solve for p.

35 = 1.0775p

divide boht side by 1.0775 to find the original price.

p = 32.48

the amount of tax is 35 - 32.48 = 2.52

this is the formula that I have always used since high school:

% / 100% = is / of

7.75% / 100% = n / $35

you sove for n = (35 x 7.75)/100

= 2.71

hope this helps :)

Here's what i think

Tax is 7.75%

Let "x" represent the original price of the item

So,

35 = x + 0.0775x

35 = x (1+0.0775)

35 = 1.0775x

x = 35/1.0775

x = 32.48

The original price was $32.48

35 X 0.0775 = amount of tax

subtract that from 35, and you get the answer for item price.

7.755 = .0775

if you put a 1 in front of .0775 (1.0775) you get a total

35*1.0775 = 37.7125

your tax was 2.7125

Where "x" is the initial price of the item.

x + x*.075 = 35

Solve for x

x*(1 + .075) = 35

x = 35/(1 + .075)

Solved for x ==> x = $32.558 Rounded = $32.56

Initial price of the item is $32.56

Tax = $35.00 - $32.558 = $2.44

Answer $2.44

lets say you pay 100A$ without tax A*7.5/100 is tax. So you give 107.5 A.

107.5A$=35$ A=32.55814
