You can put this solution on YOUR website!
Profit = Revenue - Cost
Let +n+ = number of burgers sold in one week
For a one week period:
+P+=+R+-+C+
+R+=+1.8n+
+C+=+.95n+%2B+475+
+P+=+1.8n+-+%28+.95n+%2B+475+%29+
+P+=+1.8n+-+.95n+-+475+
+P+=+1.75n+-+475+
The "break even point" ( zero profit ) is when:
+P+=+0+
+1.75n+-+475+=+0+
+1.75n+=+475+
+n+=+271.43+
That means 272 burgers must be sold before
there is a profit
--------------------
check:
+P+=+1.75n+-+475+
+n+=+272+
+P+=+1.75%2A272+-+475+
+P+=+476+-+475+
+P+=+1+
Looks OK
