A dance instructor charges according to the number of participants, if there are 10 participants or below, the instructor charge ₱600.00 for each participant per month. If the number of participants is between 10 and 20, he charges ₱500.00 for each participant per month. If there are 25 participants or more, he charges ₱450.00 for each participant per month. Write the piecewise function that describes what the instructor charges.
