Question

A movie store sells DVDs for $11 each. What is the cost C of n DVDs? Identify the situation as discrete or continuous.
A. C = 11n; continuous
B. C = 11 + n; discrete
C. C = 11 + n; continuous
D. C = 11n; discrete

Answer 1

Each DVD (n) is 11$, so therefore, the total cost is

C = 11n; discrete

Answer 2
