Math, microeconomics or criminal justice
100 -20%= 80%
80-30% of 80% = 80-24= 56% of the original price = final sales price
if the jeans originally cost $100, you now pay "only" $56
20% off mean down to $80
30% off $80 meant subtract .3(80) = $24
80-24 = $56
use another original price for the jeans, such as $10
20% would leave $8
30% off of $8 would mean subtract .3(8) =$2.40
$8- $2.40 = $5.60 as the final sales price
which is 56% of the original $10 price
