Advanced Math practice question
A video's view count is modeled by v(n) = 10 · 2ⁿ, where n is the number of days since posting. How many views does the model give for day 3?
Answer: 80
v(3) = 10 · 2³ = 10 · 8 = 80 views.
Common wrong answers
- If you answered 30
- The model multiplies by 2 each day rather than adding 10.
- If you answered 40
- 40 is day 2's count; one more doubling gives 80.
- If you answered 60
- 2³ = 8, not 6: the views double three times from 10.
