    352 ft $7.56 508 mm

    Step-by-step explanation:

    1. Starting with the equation ...

    1 in = 11 ft

    You can multiply both sides by 32 to get the answer to your question:

    32 in = 352 ft

    The actual length of the steamboat was 352 feet.

    __

    2. There are 16 ounces in a pound, so the cost is ...

    $0.21/oz * 16 oz/lb * 2.25 lb = $ (0.21*16*2.25) = $7.56

    A 2.25 lb bag of peanuts will cost $7.56.

    __

    3. Using the given conversion factors, we have ...

    (20 in) * (2.54 cm/in) * (10 mm/cm) = (20*2.54*10) mm = 508 mm

    There are 508 mm present in 20.0 inches.
