You can put this solution on YOUR website!
The break even point is where profit, +P+=+0+
and +P+=+S+-+C+ ( sales minus cost )
Let +n+ = th number of baskets sold
+S+=+10n+
+C+=+3.75n+%2B+75+
+S+-+C+=+10n+-+%28+3.75n+%2B+75+%29+
----------------------------------
Set +S+-+C+=+0+
+10n+-+%28+3.75n+%2B+75+%29+=+0+
+10n++-+3.75n+-+75+=+0+
+6.25n+=+75+
+n+=+12+
12 must be sold to break even
