Question

Last year a large trucking company delivered 8.0 x 105 tons of goods with an average value of $30,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation.

Answer 1

For a total value we have to multiply the number of tons by the average value per ton:
8.0 * 10^5 * $30.000=
= 8 * 3 * 10^5 * 10^4 =
= 24 * 10^9 =
= $ 2.4 * 10^10
Answer: The total value of the goods delivered is $2.4 * 10^10.
