Question

write inequalities to represent the situations below.
the temperature inside the lab refrigerator is less than 40 °f.
use t to represent the temperature (in °f) of the refrigerator.

to be eligible for financial aid, a student must earn no more than $15,000 per year.
use s to represent the yearly earnings (in dollars) of a student eligible for financial aid.

Explanation:

Step1: Analyze the first situation

The temperature \( t \) is less than \( 40^\circ\text{F} \), so the inequality is \( t < 40 \).

Step2: Analyze the second situation

The yearly earnings \( s \) must be no more than \( \$15,000 \), which means \( s \) is less than or equal to \( 15000 \), so the inequality is \( s \leq 15000 \).

Answer:

First inequality: \( t < 40 \)
Second inequality: \( s \leq 15000 \)
