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
2.57 x 10^0

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