Question

Write a function for the situation. Is the graph continuous or discrete?

A movie store sells DVDs for $11 each. What is the cost, C, of n DVDs?

Answer 1

Alrighty, so, 11n=C because n=DVDs time 11 per DVD equals the total cost!

Hope this helps! (:

Answer 2

`C=11n`

The cost needs to be equal to the amount of DVDs * 11 since they are $11 each. So if you had bought two:


`C=2(11) = 22`
