Two-fifths of the seats in an auditorium that holds 500 people are currently taken. It was found that 1/10 of the seats are broken. How many seats are still available?
500/ 2/5 = 200 seats are already taken.
500/ 1/10 = <<500/1/10=50>>50 seats are broken.
So 200 + 50 = <<200+50=250>>250 seats are either taken or broken.
Therefore, 500 - 250 = <<500-250=250>>250 seats are still available.
