Answer:

Rate = 58007956.5217

Step-by-step explanation:

Solving (c): The rate of change:

In this concept, the formula to use is:

Rate = \frac{V2 - V1}{t2 - t1}

Where

(t1,v1) = (0,62817000) ----- In 2004

(t2,v2) = (23,1397000000) ------ In 2026

So, we have:

Rate = \frac{1397000000 - 62817000}{23 - 0}

Rate = \frac{1334183000}{23}

Rate = 58007956.5217
