Here's an example. I see a pair of jeans that are 25% off and the regular price is, let's say $29.99. How do I figure out the cost once I take away the 25%? And how do I do the tax thing if here the tax is 8 cents?

Oops, I meant 8% tax but I'm sure you all knew what I meant!

u times 29.99 by wat u will pay which will be 75% or 0.75
and
u divide 8 by 29.99 then times by 100 and that will giv u the percentage tax

If the jeans are 25% off the regular price, it means you're getting them for 75% (100 minus 25 equals 75) of $29.99 which is 29.99 * 75/100 = $22.49.
As for the tax, I believe you meant 8% and not 8 cents. So you deduct 8% from $22.49 which is 22.49 * 8/100 = 1.80
So you end up paying 22.49 - 1.80 = $20.69
Clear!? :)

Assuming that you do not have a calculator in the store.
Round up to $30.
Divide 30 by 2 = 15
Divide 15 by 2 =7.50
If you divide by 2, then do it again. You get 25%.
30 - 7.50 = 22.50
Again to estimate 8% is close to 10%.
To take 10% of something, just move the decimal one place to the left. 22.50 becomes 2.25.
The tax would be a little less than 2.25.
22.50 + 2.50 = 25.00 This won't be exact. But it will get you close.
If you have a calculator, the quick way is to
multiply 29.99 by .75 = 22.49
the multiply 22.49 by 1.08 = 24.29

Some states have the sales tax on pre-sale prices, so let's assume that.
0.75*29.99+0.08*29.99=$24.89.
It was probably the pre-sale price tax thing throwing you off, but here's a breakdown of common % offs.
25% off means it costs 75% of the regular price.
50% off means it costs 50% of the regular price.
75% off means it costs 25% of the regular price.
90% off means it costs 10% of the regular price.

Data- Regular price = 30 ; rebate @ 25% ; tax @ 8% to the cost price.
Now it is easy to find the Selling price ie., SP= RP-(RP* rebate)
=30-(30*25%)=30-(30*25/100)=22.5
And to find the cost price (CP), let 'x` be the CP.
Then,Regular price (RP), 30=x + x *8%=x+(x*8/100)
ie., 30 =(x*108)/100 ;
Consequently, x=3000/108
Tax paid on this cost price is =(3000/108)*( 8/100)
=2.22... ( may be $, lb, Rs...)

If you have a calculator with you, good. Take your regular price and divide by 4 ( 25 o/o = 1/4) then subtract your answer from your regular price. This amount is the discounted price and the tax payable will be added to this amount. :)

25% off. So you have to deduct 25% from the original amount. 25% is equals to 0.25 of the original amount. So you multiply 29.99 by 0.25, which is around 7.50 (7.4975, but we dont have 0.25 cents change). then you minus this from your original amount of 29.99. 29.99-7.50 = 22.50.
So you only have to pay 22.50.
If the tax is originally 8 cents, that means 0.08 dollars from the original amount of 29.99. so you divide 0.08 by 29.99 to get the percentage of the tax by the whole amount. 0.08/29.99 = 0.002667. So percentage of tax = 0.2667%, which is kinda small.

FIrst Round up. 30.00 take 25% of that.
25% of 30.00 is (multiply) 6.15
so 6.15 is 25% of 30.00
subtract that from 30.00
-6.15
is $23.85
then you add then tax
multiply again 23.85 X 8% is 1.90
so 1.90 is your tax
add them together 23.85
1.90
the jeans cost 25.75
I think, I was just winging it with the numbers so do it for youself to be sure.
