The correct answer is c
Just multiply 22000 by 4.5 and then write it in the scientific notation 

Answer:

Option C - [tex]9.9 \times 10^9[/tex]

Step-by-step explanation:

Given : last year a large trucking company delivered [tex]4.5\times10^5[/tex] tons of goods with an average value of $22,000 per ton.

To find : What was the total value of the goods delivered?

Solution : Let the average value per ton =t

Average  value of the goods is  $22,000 per ton(t),

[tex]=\frac{2.2\times 10^4}{t}[/tex]

Good delivered is [tex]4.5\times10^5[/tex] tons (t).

Total value [tex]=\frac{2.2\times 10^4}{t}\times 4.5\times10^5[/tex]

Total value [tex]=2.2\times 4.5 \times 10^9[/tex]

Total value [tex]=9.9 \times 10^9[/tex]

Therefore, Option C is correct.
