Question 771318
If I add up the total gallons,
{{{ 13 + 15 + 16 + 21 + 21 + 22 = 108 }}}
If I subtract away the {{{ 15 }}}, I get
{{{ 108 - 15 = 93 }}}
he gives {{{ (1/3)*93 = 31 }}} gallons to Randy
The remaining {{{ (2/3)*93 = 62 }}} gallons to Lisa
He keeps 15 gallons of blue punch
-----------------------------
I notice also that {{{ 108 - 21 = 87 }}} and
{{{ (1/3)*87 = 29 }}}
{{{ (2/3)*87 = 58 }}}
That means the blue punch could be in
one of the 21 gallon jugs.
