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

$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.

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.
