Question 1079825
Let {{{ x }}} = his body weight at the beginning.
He lost {{{ .0809x }}} of his body weight. That
means he has {{{ ( 1 - .0809 )*x = .9191x }}} pounds left.
-----------------------------------------------
Then he lost {{{ 1.4 }}} pounds
He has {{{ .9191x - 1.4 }}} pounds left
----------------------------------------
At this point he has lost {{{ .0874x }}} pounds
That means he has {{{ ( 1 - .0874 )*x = .9126x }}} pounds left
--------------------------------------------------------
I can say:
{{{ .9191x - 1.4 = .9126x }}}
{{{ .0065x = 1.4 }}}
{{{ x = 215.385 }}}
He weighed 215.385 pounds at the beginning
--------------------------------------------
check:
He lost {{{ .0809*215.385 = 17.4246 }}}
---------------
He lost {{{ 1.4 }}}  more
{{{ 1.4 + 17.4246 = 18.8246 }}}
---------------
{{{ 18.8246 = .0874*215.385 }}}
{{{ 18.8246 = 18.8246 }}}
OK
