<PRE><B>Question 1009303</B>
Let {{{ x }}} = pounds of chamomile tea needed
-----------------
{{{ ( 18.5x + 12.26*18 ) / ( x + 18 ) = 14.18 }}}
{{{ 18.5x + 220.68 = 14.18*( x + 18 ) }}}
{{{ 18.5x + 220.68 = 14.18x + 255.24 }}}
{{{ 4.32x = 34.56 }}}
{{{ x = 8 }}}
8 pounds of chamomile tea are needed
---------------
check:
{{{ ( 18.5*8 + 12.26*18 ) / ( 8 + 18 ) = 14.18 }}}
{{{ ( 148 + 220.68 ) / 26 = 14.18 }}}
{{{ 368.68 = 14.18*26 }}}
{{{ 368.68 = 368.68 }}}
OK</PRE>
