Answer :
Sure! Let's work through the problem step-by-step.
We have a tire with a recommended pressure of 32 PSI (pounds per square inch). The question is asking when the Tire Pressure Monitoring System (TPMS) should light up to warn the driver. Typically, such systems are designed to alert the driver when the tire pressure falls significantly below the recommended level.
In this case, the TPMS should activate when the tire pressure is 25% below the recommended level. To find out what this threshold pressure is, we'll follow these steps:
1. Find 25% of the Recommended Pressure:
First, calculate 25% of the recommended pressure (32 PSI):
[tex]\[
32 \times 0.25 = 8
\][/tex]
2. Subtract This Value from the Recommended Pressure:
Next, subtract this 8 PSI from the recommended pressure to find the threshold pressure at which the TPMS should activate:
[tex]\[
32 - 8 = 24
\][/tex]
3. Identify the Correct Answer:
Based on our calculation, the TPMS should light the lamp when the tire pressure reaches 24 PSI.
Therefore, the correct answer is:
A. 24 PSI
