Question 1106873
Let {{{ x }}} = pounds of sugar to make 25% syrup
{{{ x / 5 = .25 }}}
{{{ x = 1.25 }}}
1.25 pounds of sugar, 3.75 pounds of water
--------------------
{{{ x/5 = .75 }}}
{{{ x = 3.75 }}}
3.75 pounds of sugar, 1.25 pounds of water
--------------------
{{{ x/5 = .015 }}}
you can finish
=====================
Let {{{ x }}} = water to be added
{{{ .5/( x + .5 ) = .2 }}}
{{{ .5 = .2*( x + .5 ) }}}
{{{ .5 = .2x + .1 }}}
{{{ .2x = .4 }}}
{{{ x = 2 }}}
2 pounds of water are needed
------------------------------
{{{ .5 /( x + .5 ) = .25 }}}
{{{ .5 = .25x + .125 }}}
{{{ .25x = .375 }}}
{{{ x = .375 / .25 }}}
You can finish now
