<PRE><B>Question 624901</B>
The 3 passengers get 
{{{ 3 }}} bottles of Vitamin water = {{{ 3*1.49 }}}
{{{ 3 }}} cliff bars = {{{ 3*1.79 }}}
2 passengers get
{{{ 2 }}} Dr Peppers = {{{ 2*1.2 }}}
{{{ 2 }}} Doritos = {{{ 2*.99 }}}
------------------------
This adds up to
{{{ 3*1.49 + 3*1.79 + 2*1.2 + 2*.99 }}}
{{{ 4.47 + 5.37 + 2.4 + 1.98 = 14.22 }}}
Let {{{ x }}} = number of bags of Skittles they can buy
{{{ 14.22 + .88x = 18.5 }}}
{{{ .88x = 4.28 }}}
{{{ x = 4.86 }}}
They can buy 4 bags of Skittles</PRE>
