Bob is in charge of doing laundry for a large hotel. Each room has two sheets, one comforter, twice as many pillow cases as sheets and twice as many towels as pillow cases. How many pieces of laundry are there in 80 rooms?
First find the number of pillow cases in each room: 2 sheets * 2 pillow cases/sheet = 
<gadget id="calculator">2*2</gadget>
<output>4</output>
4 pillow cases.
Then find the number of towels in each room: 4 pillow cases * 2 towels/pillow case = 
<gadget id="calculator">4*2</gadget>
<output>8</output>
8 towels.
Then find the number of pieces of laundry in each room: 4 pillow cases + 8 towels + 2 sheets + 1 comforter = 
<gadget id="calculator">4+8+2+1</gadget>
<output>15</output>
15 pieces of laundry.
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 =
