Question 1155959
Let {{{ x }}} = amount he started with
After spending 2/5, he has {{{ (3/5)*x }}}
------------------------------------------
Then he bought a coat, and he has left:
{{{ ( 3/5)*x - ( (2/5)*x - 6 ) }}}
And you are given:
{{{ ( 3/5)*x - ( (2/5)*x - 6 ) = 37 }}}
{{{ ( 3/5 )*x - ( 2/5 )*x + 6 = 37 }}}
{{{ ( 1/5)*x = 31 }}}
{{{ x = 155 }}}
He started with $155
----------------------------
check:
$155 to start with
He spends {{{ (2/5)*155  = 62 }}}
He has {{{ 155 - 62 = 93 }}}
$93 left
and for the coat:
{{{ 62 - 6 = 56 }}}
$56 is spent
{{{ 93 - 56 = 37 }}}
He has $37 left
OK
