Answer 1

Answer: -1.60%

Step-by-step explanation:

1. You know that:

-  The sum of the stocks in the Dow Jones was $10,289.57.

- The sum of the stocks in the Dow Jones was $10,124.19 at the end of the day.

2. Keeping this on mind, you can calculate the rate of change of the Dow Jones on that particular day as following:

$ROC=(\frac{10,124.19-10,289.57}{10,289.57})*100\\ROC=(\frac{-165.38}{10,289.57})*100\\ROC=-1.60%$

3. Therefore, the answer is -1.60%.
