Answer:
20
Step-by-step explanation:
6,460 divided by 323 = 20
25.05 I would think mean .05 is the change and if there is not a month cost than it would not double
Expression is: 2.2 × 10⁴ / 8.8 × 10⁹
= 1 × 10⁴ / 4 × 10⁹
= 0.25 × 10⁴⁻⁹
= 0.25 × 10⁻⁵
= 2.5 × 10⁻⁶
In short, Your Answer would be: Option D
Hope this helps!
