Sanjay and his friends are doing a physics lab on air pressure. First, they fill a balloon with air until it reaches a pressure of 300 kilopascals. Then they poke the balloon and measure its pressure over time. According to their measurements, the balloon appears to be losing pressure at a rate of 15% every hour. If this trend continues, what will the pressure be in 8 hours?
If necessary, round your answer to the nearest tenth
