Hi there!
a.
To find the total amount of people that have ENTERED by t = 20, we must take the integral of the appropriate function.
Evaluate using a calculator:
b.
To solve, we can find the total amount of people that have entered of the interval and subtract the total amount of people that have left from this value.
In other terms:
We can evaluate using a calculator (math-9 on T1-84):
c.
If:
Then:
Evaluate at t = 20:
This means that at t = 20, there is a <u>NET DECREASE</u> of people at the movie theater of around 20.823 (21) people per hour.
d.
To find the maximum, we must use the first-derivative test.
Set S(t) - R(t) equal to 0:
Graph the function with a graphing calculator and set the function equal to y = 0:
According to the graph, the graph of the first derivative changes from POSITIVE to NEGATIVE at t ≈ 17.78 hours, so there is a MAXIMUM at this value.
<u>Thus, at t = 17.78 hours, the amount of people at the movie theater is a MAXIMUM.</u>

Hi!
Your answer is C.
A is an example because it's not good to only make identify one solution; you need backups or a variety of ways.
B is an example because, hey, not everything is true! Especially on the internet. Questioning source information is great because then you are sure what you are seeing is unbiased and accurate.
C is NOT an example. As stated above, you need a variety of solutions, but you can't just pick the first solution; you want to pick the <em>best</em> solution for the problem at hand.
D is an example. As stated above, questioning source information is great, but then you need to also verify it, because, like said before, not everything is true.
