Last year a large trucking company delivered 3.0*10^5 tons of goods with an average value of $30,000 per ton. What was the total value of goods delivered? Write the answer in scientific notation.

A. 9.0*10^11 dollars
B. 9.0*10^8 dollars
C. 9.0*10^9 dollars
D. 9.0*10^10 dollars

30,000 = 3.0*10^4

3.0*10^5 * 3.0*10^4 = 9.0*10^9

To find the total value of goods delivered, we need to multiply the quantity of goods by their value per ton. In this case, the company delivered 3.0*10^5 tons of goods, with an average value of $30,000 per ton.

To multiply two numbers expressed in scientific notation, we can multiply their coefficients (the numbers before the power of 10), and then add their exponents (the powers of 10). Let's calculate the total value:

3.0 * 10^5 tons * $30,000/ton

First, we multiply the coefficients:
3.0 * $30,000 = $90,000

Next, we add the exponents:
10^5 * 10^0 = 10^(5+0) = 10^5

Finally, we write the total value in scientific notation:
$90,000 * 10^5 = 9.0 * 10^4 * 10^5 = 9.0 * 10^(4+5) = 9.0 * 10^9

Therefore, the total value of goods delivered is 9.0*10^9 dollars. So, the answer is C. 9.0*10^9 dollars.
