Question

write inequalities to represent the situations below.
to be eligible for the senior admission rate, a visitor must not be less than 65 years old.
use y to represent the age (in years) of a visitor who gets the senior rate.

the temperature inside the lab refrigerator is at most 45 °f.
use t to represent the temperature (in °f) of the refrigerator.

inequality symbols and buttons on the right side: <, >, ≤, ≥, undo, close

Explanation:

Step1: Define senior age condition

"Not less than 65" means age is 65 or older.
$y \geq 65$

Step2: Define fridge temp condition

"At most 45" means temp is 45 or lower.
$t \leq 45$

Answer:

1. $y \geq 65$
2. $t \leq 45$
