Question 1057724
Let {{{ x }}} = ounces of salt you need to add
{{{ x / ( 8 + x ) = .035 }}}
{{{ x = .035*( 8 + x ) }}}
{{{ x = .28 + .035x }}}
{{{ .965x = .28 }}}
{{{ x = .2902 }}}
---------------------
You need to add .2902 ounces of salt
( .29 or .3, whatever the limits of accuracy are )
---------------------
check:
{{{ x / ( 8 + x ) = .035 }}}
{{{ .2902 / ( 8 + .2902 ) = .035 }}}
{{{ .2902 = .035*8.2902 }}}
{{{ .2902 = .29016 }}}
