~~~~~~~~~~~~~~~


<pre>
x packets at $2.48  and  16-x packets at #4.88.


Write the "money equation"

    2.48x + 4.88*(16-x) = 3.53*16  dollars


Simplify and find x

    2.48x + 4.88*16 - 4.88x = 3.53*16

         2.48x - 4.88x      = 3.53*16 - 4.88*16

               x            = {{{(3.53*16 - 4.88*16)/(2.48-4.88)}}} = 9.


<U>ANSWER</U>.  In the assortment, there are 9 packets at $2.48 and 16-9 = 7 packets at $4.88.
