C = 11n; continuous
C = 11 n ; continuous

C = 11 + n; discrete
C = 11 + n ; discrete

C = 11 + n; continuous
C = 11 + n ; continuous

C = 11n; discrete

C = 11n; discrete

Answer 2

The formula for the cost C of n DVDs is C = 11n. This means that the cost of the DVDs is calculated by multiplying the quantity of DVDs, n, by the price per DVD, which is $11.

Now, let's determine whether the situation is discrete or continuous. In this case, the quantity n represents a whole number, as you can only buy a whole number of DVDs. Therefore, the situation is discrete, since it deals with a countable number of items.

So, the correct answer is: C = 11n; discrete.

The cost of n DVDs can be calculated using the equation C = 11n. In this situation, the cost is directly proportional to the number of DVDs, so it is continuous.
