Try something like this:
t = {0, 1, 1.5, 2, 2.5, 4, 6, 8, 10, 15, 20, 30};
Remove @@ Names["tc*"]
(Evaluate@Symbol["tc" <> ToString@#] = {0}~Join~(Rest[t] - #/100.)) & /@
\
Range[15, 30, 5];
?tc*

Dear Colleagues,
I have a t-vector
t = {0, 1, 1.5, 2, 2.5, 4, 6, 8, 10, 15, 20, 30};
I want to subtract 0.15 from each element except the first to get
tc15 = {0, 1 - 0.15, 1.50 - 0.15, 2 - 0.15, 2.5 - 0.15, 4 - 0.15, 6 -
0.15, 8 - 0.15, 10 - 0.15, 15 - 0.15, 20 - 0.15, 30 - 0.15};
I then want to subtract 0.20 to get
tc20 = {0, 1 - 0.20, 1.50 - 0.20, 2 - 0.20, 2.5 - 0.20, 4 - 0.20, 6 -
0.20, 8 - 0.20, 10 - 0.20, 15 - 0.20, 20 - 0.20, 30 - 0.20};
Is there a way to automate this process for n subtractions from 0.15
to 0.30 to yield individual t-vectors for tc15 through tc30 ?
With Much Appreciation,
Oscar
