Question

1. if a park closes at sunset, which is no later than 8 pm, how should this be written as an inequality for closing time $t$?

a. $t \geq 8$ pm
b. $t \leq 8$ pm
c. $t < 8$ pm
d. $t > 8$ pm

Explanation:

Step1: Interpret "no later than 8 PM"

This means closing time $t$ can be 8 PM or earlier.
