Humans have a normal body temperature of 98.6°F. A temperature, x, that differs from normal by at least 2°F is considered unhealthy. Which inequality could be used to determine whether a temperature is unhealthy?

A.|x − 98.6| ≤ 2

B.|x − 98.6| > 2

C.|x − 98.6| ≥ 2

D.|x − 98.6| < 2

Since your question says "A temperature, x, that differs from normal by** at least 2°F **is considered unhealthy", then how do you write " at least" in the 4 choices given to you?

I would say "C" and ≥ 2, because that means **"equal to or greater than 2"**. In other words it says **"at least".**
