Answer 1

Answer:

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
