Question

a t < 82
b t ≤ 82
c t > 82
d t ≥ 82

Explanation:

To determine the correct inequality, we analyze the context (though not provided here, typically in such problems, if we need values greater than or equal to 82, the symbol $\geq$ means "greater than or equal to". Option D has $t \geq 82$, which includes 82 and values above it.

Answer:

D. $t \geq 82$
