Question

You can increase your subscriber count by increasing the viewer retention rates for future videos. Viewer retention rates measure the percentage of viewers who stay watching your videos over time.

If your current viewer retention rate is 73% (or 0.73), and this rate increases by 0.2% (or 0.002) for each uploaded video, which expression represents your viewer retention rate after you’ve uploaded v videos?
Question 11 options:

0.73v + 0.002

0.002v +0.73

0.73 + 0.002/v

0.73 + v/0.002

Answer 1

0.002v + 0.73

Start at 0.73 and add 0.002 for each of the v videos, so the rate is 0.73 + 0.002·v (which is the same as 0.002v + 0.73).
