Question 1005718
Let {{{ x }}} = overtime hrs that Andrew worked
{{{ x + 12 }}} = overtime hrs that Ellen worked
-------------------------------------
{{{ ( x + 12 ) / x = 8/5 }}}
{{{ 5*( x + 12 ) = 8x }}}
{{{ 5x + 60 = 8x }}}
{{{ 3x = 60 }}}
{{{ x = 20 }}}
and
{{{ x + 12 = 20 + 12 }}}
{{{ x + 12 = 32 }}}
Ellen worked 32 hrs overtime
Andrew worked 20 hrs overtime
---------------------------
check:
{{{ ( x + 12 ) / x = 8/5 }}}
{{{ 32 / 20 = 8/5 }}}
{{{ ( 8*4 ) / ( 5*4 ) = 8/5 }}}
{{{ 8/5 = 8/5 }}}
OK
