Answer:
The answer is 9.9 × 10⁹ dollars.
Step-by-step explanation:
To solve this problem, first, you have to multiply the tons delivered by the trucking company with the average value of a ton.
Then, you have:
4.5 × 10⁵ tons · 22.000 dls/tons // tons/tons = 1 ; 22.000 = 22 × 10⁴ in scientific notation
4.5 × 10⁵ · 22 × 10⁴ dls // solve by definition 10⁵ · 10⁴ = 10⁹
(4.5·22) × 10⁹ = 9.9 × 10⁹ dls.
