Question 1103727
Let {{{ x }}} = pounds of peanuts needed
-------------------------------------
{{{ ( 6x + 15*100 ) / ( x + 100 ) = 8 }}}
{{{ 6x + 1500 = 8*( x + 100 ) }}}
{{{ 6x + 1500 = 8x + 800 }}}
{{{ 2x = 700 }}}
{{{ x = 350 }}}
-------------------------
350 pounds of peanuts are needed
--------------------------------
check:
{{{ ( 6*350 + 1500 ) / ( 350 + 100 ) = 8 }}}
{{{ ( 2100 + 1500 ) / 450 = 8 }}}
{{{ 3600 / 450 = 8 }}}
{{{ 3600 = 3600 }}}
OK
