Textbook Problem Salary Contract A union contract guarantees an 11% yearly salary increase for 5 years. For a current salary of $45,300, the salaries S for the next 5 years are given by S45, 300(1.11) where t 0 represents the present year. (a) Use the greatest integer function of a graphing utility to graph the salary function and then discuss its continuity. (b) Find the salary during the fifth year (when t= 5).
