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?
A. C = 11 + n; discrete
B. C = 11n; continuous
C. C = 11 + n; continuous
D. C = 11n; discrete

Answer 1

B: because 11 times N will give you how much your cost would be . Example: 11*2= $22 if you bought 2 cds it would be $22. and its continuous cause youre going up at a constant rate.
