Question 851436
Let {{{ x }}} = number she had when she left grove
She gave {{{ x/2 + 3 }}} to jennifer, so she had
{{{ x - ( x/2 + 3 ) }}} left
------------------------
She gave {{{ (1/2)*( x - x/2 - 3 ) + 3 }}} 
{{{ (1/2)*x - (1/4)*x - 3/2 + 3 }}}
{{{ (1/4)*x + 3/2 }}} to Angela, so she has left:
{{{ x/2 - 3 - ( (1/4)*x + 3/2 ) }}}
{{{ x/2 - 3 - (1/4)*x - 3/2 }}}
{{{ (1/4)*x - 9/2 }}}
---------------------
She gave {{{ (1/2)*( (1/4)*x - 9/2 ) + 3 }}}
{{{ (1/8)*x - 9/4 + 3 }}}
{{{ (1/8)*x + 3/4 }}} to Josie, so she has left:
{{{ (1/4)*x - 9/2 - (1/8)*x - 3/4 }}}
{{{ (1/8)*x - 21/4 }}}
--------------------
{{{ (1/8)*x - 21/4 = 10 }}}
{{{ x - 42 = 80 }}}
{{{ x = 122 }}}
---------------
She had 122 oranges when she left grove
check:
She gave {{{ 122/2 + 3 = 64 }}} to jennifer, so she had
{{{ 122 - 64 = 58 }}} left
She gave {{{ 58/2 + 3 = 32 }}} to Angela, so she had
{{{ 58 - 32 = 26 }}} left
She gave {{{ 26/2 + 3 = 16 }}} to Josie, so she had
{{{ 26 - 16 = 10 }}} left
as she should
