From the question, we have the following given parameters:
x = Amount paid for a second movie
--- Expected value of x
--- Standard deviation of x
Required
Determine the total amount paid for a second movie for 20 weeks
The required implies that we calculate the expected value for a duration of 20 weeks.
i.e.
If

Then:

Substitute 20 for n

Substitute 0.47 for E(x)


<em>Hence, the expected amount for a duration of 20 weeks is $9.4</em>
