Question 1077072
{{{ .8*75 = 60 }}} liters of milk in
the 80% solution
Let {{{ x }}} = liters of water to be added
--------------------------------------
{{{ 60 / ( x + 75 ) = .24 }}}
{{{ 60 = .24*( x + 75 ) }}}
{{{ 60 = .24x + 18 }}}
{{{ .24x = 42 }}}
{{{ x = 175 }}}
175 liters of water must be added
---------------------------------
check:
{{{ 60 / ( x + 75 ) = .24 }}}
{{{ 60 / ( 175 + 75 ) = .24 }}}
{{{ 60 / 250 = .24 }}}
{{{ 60 = .24*250 }}}
{{{ 60 = 60 }}}
OK
