Which one do you need answered
Answer: A. The expression
reveals the approximate rate of increase in the number of subscribers if measured six times a year.
Step-by-step explanation:
Here, The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscribers after t years.

where
represents rate of increase in the number of subscriber.
If rate is measured six times a year
then the number of subscriber, 
( approx)
Thus, when we measure increment in six times a year then the rate rate of increase in the number of subscribers=
Therefore Option A is correct.
Note: Option B) is incorrect because rate of increase in the number of subscribers if measured three times a year =
( approx)
Option C) is incorrect because rate of increase in the number of subscribers if measured four times a year =
( approx)
Option D) is incorrect because rate of increase in the number of subscribers if measured two times a year =
( approx)
We could represent this as an equation:
47x = $209, where x is the number of lawns mowed.
What we could do is divide 209 by 47 to find out how many lawns Jerry would need to mow. This would give us about 4.4 (when rounded). Since Jerry has to mow entire lawns, we would have to round that up to 5 lawns. Jerry would earn $235 for those, which is more than enough for those new video games.
