You can put this solution on YOUR website!
Let +P+ = profit for day
Let +n+ = number of tacos sold/day
--------------
+P+=+3.25n+-+210+
Profit needs to be positive, so
+3.25n+%3E+210+
+n+%3E+210%2F3.25+
+n+%3E+64.615+
They can only sell whole tacos, so
they must sell at least 65 tacos to make a profit
That profit is:
+P+=+3.25n+-+210+
+P+=+3.25%2A65+-+210+
+P+=+211.25+-+210+
+P+=+1.25+
$1.25 profit
