Answer: question 1- C and D, question 2- B
Explanation:
since she wants to find the amount of subscribers per amount of content, we want to use data points from content. this is why option C and D are correct, as numbers of posts and number of words are datapoints determined by content, not viewer engagement or other irrelavent points.
for the second question, you want to use te number of subscribers as the numerator and the other data as the denominator. for website A, tis is 9000/110 and 9000/100. for website B, it is 20000/200 and 20000/170. when simplified, both of website Bs data points/subscriber are larger than website As, meaning website B gains more subscribers per month.
hope this helps!!
