You can put this solution on YOUR website!
Let profit = +P%28x%29+
+P%28x%29+=+R%28x%29+-+C%28x%29+
+P%28x%29+=+15x+-+%28+5x+%2B+20+%29+
+P%28x%29+=+15x+-+5x+-+20+
+P%28x%29+=+10x+-+20+
------------------
given:
+P%28x%29+=+500+
+500+=+10x+-+20+
+10x+=+520+
+x+=+52+
52 tacos sold make a $500 profit
