Question 1152629
Let {{{ x }}} = amount Mary spends
{{{ 2x - 5 }}} = amount Danny spends
--------------------------------------
{{{ x + 2x - 5 = 70 }}}
{{{ 3x - 5 = 70 }}}
{{{ 3x = 75 }}}
{{{ x = 25 }}}
and
{{{ 2x - 5 = 2*25 - 5 }}}
{{{ 2x - 5 = 50 - 5 }}}
{{{ 2x - 5 = 45 }}}
---------------------------
Mary spends $25
Danny spends $45
----------------------
check:
{{{ 25 + 45 = 70 }}}
{{{ 70 = 70 }}}
OK
