whats the easiest way to figure out the price on a discount item.
i know how to do it but there are to many steps : )
for ex- boom box 4.95 30% off how much would the final price be?
Also what about tax?
if something was 99.75 and u also have to pay 8% tax
how much cash would u get back if you gave the person 120.00

Since it is 30% off, that means you are paying 70% of the original price.
144.95(.70) = 101.465, which you would round to 101.47
The other way to do this kind of problem is to multiply 144.95 times .3
144.95(.30) = 43.485
Now subtract that from the original price.
144.95 – 43.485 = 101.465 which rounds to 101.47
2) If something was 99.75 and u also have to pay 8% tax,
how much cash would u get back if you gave the person 120.00?
Take 99.75 times 1.08. This will give you the total.
99.75(1.08) = 107.73
Then subtract that amount from 120.
120.00 – 107.73 = 12.27
You would get $12.27 back.

Just move the decimal place over by one (to get 10%), and then multiply that by the discount.
$144.95 —-> $14.49 (is 10%) X 3 = $43.48
$144.95 – $43.48 = $101.47 (final price)
3 steps.

$144.95 – 30 % = $ 43.49 off so it would be $ 101.46

$144.95 x .7 is the quickest way to get there.

$144.95 30% off
remember that % means divided by 100 so 30%=.30
if you take 30% off, that leaves 1-.3=.7=70% left. Multilple the price by .70
$144.95*.7=$101.47

‘
you are paying 70% of the price:
144.95(.70) = 101.465,

you are paying 70% of the price, i.e.
144.95 x 0.7
