Question 668738
Let {{{ x }}} = pounds of $5 per pound candy needed
{{{ 5x }}} = amount spent on $5 per pound candy
{{{ 4*60 = 240 }}} = amount spent on $4 per pound candy
--------------
{{{ ( 5x + 240 ) / ( x + 60 ) = 4.4 }}}
{{{ 5x + 240 = 4.4*( x + 60 ) }}}
{{{ 5x + 240 = 4.4x + 264 }}}
{{{ .6x = 24 }}}
{{{ x = 40 }}}
40 pounds of $5 per pound candy are needed
check:
{{{ ( 5*40 + 240 ) / ( 40 + 60 ) = 4.4 }}}
{{{ ( 200 + 240 ) / 100 = 4.4 }}}
{{{ 440 = 100*4.4 }}}
{{{ 440 = 440 }}}
