Adding \( 5 \) rows at \( 6 \) abreast increases capacity by

  • A.11 seats
  • B.5 seats
  • C.60 seats
  • D.30 seats

Answer: D

Multiplying, \( 5 \times 6 = 30 \) seats. Whether an extra exit pair is then required depends on which certification band the new total falls into, and adding a door is expensive enough that a stretch is sometimes sized deliberately to stay below the threshold.
