You can put this solution on YOUR website!
Let +C+ = cost of renting machine in pesos
Let +n+ = number of days it is rented
--------------------------------------
+C+=+1000+%2B+400%2A%28+n+-+3+%29+
You can split this up:
+C+=+C%5B1%5D+%2B+C%5B2%5D+
+C%5B1%5D+=+1000+ ( 0 < n < 3 )
+C%5B2%5D+=+400n+ ( n > 3 )
These can be plotted separately
