scientific notation

Express the answer in scientific notation to two decimals unless requested otherwise.

A company produced 2,600,000 small appliances in one year and made a profit of $6,690,000. What was the profit on each appliance?

  • scientific notation -

    $6,690,000/2600000 = $2.57 per appliance.

    I don't see why you would want to express $2.57 in scientific notation.

    2.57 x 10^1 looks just plain silly.

  • scientific notation -

    actually 2.57 x 10^1
    should read
    2.57 x 10^0

    I guess I was concentrating so much on the silly answer that I messed up my typing.
