Question 499007
In words:
( ounces of salt you end up with ) / ( total ounces of solution ) = 3%
Let {{{w}}} = ounces of water to be added
given:
{{{ .08*60 = 4.8 }}} = ounces of salt in 8% solution
---------------
{{{ 4.8 / ( 60 + w ) = .03 }}}
{{{ 4.8 = .03*( 60 + w ) }}}
{{{ 4.8 = 1.8 + .03w }}}
{{{ .03w = 4.8 - 1.8 }}}
{{{ .03w =3 }}}
{{{ w = 100 }}}
100 ounces of pure water must be added
