Answer:
![Rate = 58007956.5217](https://tex.z-dn.net/?f=Rate%20%3D%2058007956.5217)
Step-by-step explanation:
Solving (c): The rate of change:
In this concept, the formula to use is:
![Rate = \frac{V2 - V1}{t2 - t1}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7BV2%20-%20V1%7D%7Bt2%20-%20t1%7D)
Where
----- In 2004
------ In 2026
So, we have:
![Rate = \frac{1397000000 - 62817000}{23 - 0}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B1397000000%20-%2062817000%7D%7B23%20-%200%7D)
![Rate = \frac{1334183000}{23}](https://tex.z-dn.net/?f=Rate%20%3D%20%5Cfrac%7B1334183000%7D%7B23%7D)
So,
5y*3 is the open phrase the student uses to model "the sum of 5y and 3".
"The sum of" means addition. The student put 5y*3, while the sum of 5y and 3 is actually 5y + 3.
