How many pillow cases are in each room? ** First find the number of pillow cases in each room: 2 sheets * 2 pillow cases/sheet = <<2*2=4>>4 pillow cases
How many towels are in each room? ** Then find the number of towels in each room: 4 pillow cases * 2 towels/pillow case = <<4*2=8>>8 towels
How many pieces of laundry are in each room? ** Then find the number of pieces of laundry in each room: 4 pillow cases + 8 towels + 2 sheets + 1 comforter = <<4+8+2+1=15>>15 pieces of laundry
How many pieces of laundry are there in 80 rooms? ** Then multiply the number of pieces of laundry in each room by the number of rooms to find the total: 15 pieces of laundry/room * 80 rooms = <<15*80=1200>>1200 pieces
