.
<pre>

Let x be the total number of muffins Ms Teo made.


Of them,  the number of the chocolate muffins is  {{{(4/5)x}}};

          the number of the blueberry muffins is  {{{(1/5)x}}}.


After selling 84 blueberry muffins and {{{5/8}}}  of the chocolate muffins,  {{{(2/5)x}}}  of the muffin left


    {{{(4/5)x}}} - {{{(5/8)*(4/5)x}}} + {{{(1/5)x-84}}} = {{{(2/5)x}}}.


Solve the equation and find x.


Then {{{(3/5)x}}}  is your answer.
