Question 630299
Suppose an item originally cost $100
After the 1st discount,
{{{ 100 - .11*100 }}}
{{{ 100 - 11 = 89 }}}
It costs $89
---------
Then after the 2nd discount,
{{{ 89 - .08*89 }}}
{{{ 89 - 7.12 = 81.88 }}}
It costs $81.88
--------------
So, after the 2 discounts, the item ended up
costing {{{ 100 - 81.88 = 18.12 }}} less
So, the discount is {{{ (18.12/100)*100 }}} %
or 18.12 %
