EXAMPLE (^10) Timeshares Every year, the 73 part-owners of a
timeshare resort condominium get use of it for an equal number of days. How
many days does each part-owner get to stay at the condo? (Use a 365-day year.)
StrategyWe will divide 365 by 73.
WHYSince the part-owners get use of the condo for an equal number of days,
the phrase “How many days does each”indicates division.
