Question

Last year a large trucking company delivered 8.0x10^5 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

8.0x10^5
Convert scientific notation into the actual number.
800,000
Multiply 800,000 by $30,000, because 1 ton equals $30,000.
800,000 x 30,000=$240,000,000,000
Scientific notation is 2.4 x 10^11

Answer 2

$24(10)⁹

Explanation:

Last year a large trucking company delivered goods = 8.0 × 10⁵ tons

We will simplify the value = 8.0 × 10⁵

= 8.0 × 100,000

= 800,000 tons

An average value of each ton = $30,000

Therefore, the value of 800,000 tons = 30,000 × 800,000

= $24,000,000,000

= $24 billions

We will rewrite the answer in scientific notation

$24,000,000,000 = $24(10)⁹
