Question 955482
Let {{{ x}}} = amount of sales that
is over $10,000
Carol's commission is:
{{{ .05*( 10000 + x ) }}}
---------------------
For her to make $20,000:
{{{ 20000 = 15000 + .05*( 10000 + x ) }}}
{{{ 5000 = .05*( 10000 + x ) }}}
{{{ 5000 = 500 + .05x }}}
{{{ .05x = 4500 }}}
{{{ x = 450000 / 5 }}}
{{{ x = 90000 }}}
and
{{{ 10000 + 90000 = 100000 }}}
She needs to make $100,000 in sales
