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
The correct answer is:
C = 11n; discrete
In this situation, the cost C of n DVDs is found by multiplying the number of DVDs (n) by the cost of each DVD ($11). Since the number of DVDs is a whole number and the cost is determined by multiplying the number of DVDs by a fixed price, the situation is discrete.
