Question 1144856
Let {{{x}}} = the amount of food sales
{{{ .2x = 625 + .1x }}}
{{{ .1x = 625 }}}
{{{ x = 6250 }}}
$6,250 worth of food sales makes their earnings equal.
-------------------------
check:
{{{ .2x = 625 + .1x }}}
{{{ .2*6250 = 625 + .1*6250 }}}
{{{ 1250 = 625 + 625 }}}
{{{ 1250 = 1250 }}}
OK
