Question: Parameters with values in the Maple textplot

Dear Maple experts, I want to write text in a specific location within a Maple plot like p<c. To do that, I use 'plots:-textplot' as follows:

plots:-textplot([[0.1, 0.80, p < c, color = black]], font = [times, 11], rotation = 'horizontal');

The issue is that in my code, 'p' and 'c' are parameters with specific values. Therefore,  in my plot, their values appear instead of p<c. Even if I use 'p<c' or "p<c" it does not work.

Would you please guide me on how to solve the issue?
