You can put this solution on YOUR website!
Let +x+ = the most burgers he can buy
+2.25x+=+50.45+-+10+
+2.25x+=+40.45+
+x+=+17.978+
--------------------
He can't buy 18 burgers, so
he can only buy 17
-------------------------------
check:
Suppose he buys 18 burgers
+2.25%2A18+=+40.5+
and
+50.45+-+40.5+=+9.95+
He would only have $9.95 for drinks
