Salary Contracy  A union contract guarantees a 10% salary increase yearly for 3 years. For a current salary of $28.00, the salary S (in thousands of dollars) for the next 3 years is given by...
S(t)=
28.00, 0<t<1
30.80, 1<t<2
33.88, 2<t<3
where t=0 represents the present year. Does the limit of S exist as t approaches 2? Explain your reasoning.
I have no idea where to begin... Help.

Thanks.
