A movie store sells DVDs for $11 each. What is the cost C of n DVDs? Identify the situation as discrete or continuous.
answer C = 11n; discrete
how did you get the answer
To find the cost of n DVDs, you can multiply the cost of each DVD by the number of DVDs purchased. In this case, since each DVD costs $11, the cost C of n DVDs can be represented as 11n.
The situation is discrete because the number of DVDs is a discrete quantity. It is unlikely that you can purchase a fraction of a DVD.
