Question 999944
Let {{{ x }}} = amount of sales he makes in 1 week
Let {{{ A[1] }}} = his income from the 1st job
Let {{{ A[2] }}} = his income from the 2nd job
------------------
{{{ A[1] = 600 + .2x }}}
{{{ A[2] = 500 + .25x }}}
---------------------
For the jobs to pay the same:
{{{ A[1] = A[2] }}}
{{{ 600 + .2x = 500 + .25x }}}
{{{ .05x = 100 }}}
{{{ x = 100/.05 }}}
{{{ x = 2000 }}}
$2,000 in sales makes both jobs the same
----------------
check:
{{{ A[1] = 600 + .2*2000 }}}
{{{ A[1] = 600 + 400 }}}
{{{ A[1] = 1000 }}}
and
{{{ A[2] = 500 + .25*2000 }}}
{{{ A[2] = 500 + 500 }}}
{{{ A[2] = 1000 }}}
OK
