Danielle is ordering costumes for her dance recital. The company Danielle is ordering from charges $19 per costume and a shipping fee of $9.
Based on this information, which function can be used to represent the relationship between the total cost, k, and the number of costumes Danielle orders, u?
k=19u−9
k = 9u + 19
k = 19u + 9
k=9u−19
