Final answer:
To estimate the number of DVDs Aaron will sell in the 13th month, we can use the trend shown by the scatter plot. Based on the decreasing trend, the approximate predicted number of DVDs would be around 160.
Step-by-step explanation:
To approximate the predicted number of DVDs Aaron will sell in the 13th month, we can use the trend shown by the scatter plot. We can see that as the number of months increase, the number of DVDs sold decreases. Based on this trend, we can estimate that the number of DVDs sold in the 13th month would be less than the previous months. Looking at the scatter plot, it appears that the approximate predicted number of DVDs Aaron will sell in the 13th month is around 160. Therefore, the correct answer is c) 160.
