# Define the constants

priceSectionC=10

# Have user enter the number of tickets sold in Section A and validate the entry

while ticketsSoldSectionA < 0 or ticketsSoldSectionA > 300:
	ticketsSoldSectionA = input('The number of tickets sold in Section A is invalid. Please reenter a number between 0 and 300.\n')

# Have user enter the number of tickets sold in Section B and validate the entry

while ticketsSoldSectionB <0 or ticketsSoldSectionB >500:
	ticketsSoldSectionB = input('The number of tickets sold in Section B is invalid. Please reenter a number between 0 and 500.\n')

# Have user enter the number of tickets sold in Section C and validate the entry

while ticketsSoldSectionC <0 or ticketsSoldSectionC >200:
