PLZ HELP The drama teacher wants to estimate how many tickets to sell for a show. The auditorium has 56 rows of seats. There are 32 seats in each row. Which explains whether it makes more sense to find an overestimate or an underestimate to decide how many tickets to sell? A. It makes more sense to find an underestimate so that some people can enter the auditorium without buying a ticket. B. It makes more sense to find an underestimate to make sure there are enough seats for everybody who buys a ticket to the show. C. It makes more sense to find an overestimate to make sure every seat in the auditorium is filled. D. It makes more sense to find an overestimate so that the show makes the most amount of money it can.
