Simply multiply the price by the remaining percentage to be paid.  For eample, 15.95 x 70% pr 15.95 x .70 = 11.165.

You would be paying for 80% of the full price in question two, so 30.95 x .8 = 24.76

"off" means that the original price is decreased by that percentage.

1. $15.95-$15.95(.3) =  $11.17

2.$30.95-$30.95(.2) = $24.76

Those are are always estimated to the nearest cents.

If the question is just to find the sale price after the percentage has been taken off then remember that there are 2 steps to this process first you have to figure out what is the percentage of the original price then subract that from the original price to get the sale price.

I will complete 1 as an example then you should know how to do the second one on your own.

Original price = $15.95
percentage to subtract=30% (30% same as .30)

$15.95 X .30 = 4.79

$15.95 - $4.79 = sale price

sale price = $11.17

1)The original price is 100% and there is a discount of 30% so the discounted price is 70%

sale price= 70% of 15.95= $11.165

2) sale price of jeans = (100-20)% of $30.95= $24.76

15.95 multiplied by .3 = 4.785 (which rounds to 4.79)

Now subtract that from the original number= 15.95-4.79=$11.16

30.95 multiplied by .2= $6.19

Now subtract that from our original price to get the discounted price = $30.95 - $6.19= $24.76
