You can put this solution on YOUR website!
Let +p+ = p[rice in dollars for 50 in sub
+2.95+%2F+4+=+p+%2F+50+
Multiply both sides by +200+
+50%2A2.95+=+4p+
+147.5+=+4p+
+p+=+36.875+
The deli should charge $36.88
--------------------------
+4+ in is +4%2F12+=+1%2F3+ ft
The unit rate in dollars/ft is:
+2.95+%2F+%281%2F3+%29+=+8.85+
$8.85 / ft
