Question

question 16 of 40
the target temperature for a laboratory is 68° fahrenheit. it can vary by up to 4°. if t is the temperature in the laboratory, which of the following inequalities represents this situation?
a. |t + 4| ≤ 68
b. |t − 4| ≥ 68
c. |t − 68| ≤ 4
d. |t + 68| ≤ 4

Explanation:

Step1: Define temperature variation

The difference between actual temp \(t\) and target \(68^\circ\) is at most \(4^\circ\).
This means \(|t - 68| \leq 4\).

Step2: Match with options

Compare the derived inequality to the choices.

Answer:

C. \(|t - 68| \leq 4\)
