I am sorry can you explain it more?
Answer:
<h2>377 kPa</h2>
Explanation:
The original pressure can be found by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the original pressure

150 kPa = 150,000 Pa
We have

We have the final answer as
<h3>377 kPa</h3>
Hope this helps you
