#"76. kPa"#.

Explanation:

Boyle's Law The pressure is inversely proportional to volume.
As the volume is decreasing the pressure must be increasing.

# P_1xxV_1 = P_2 xx V_2# substituting the given values gives

# 49 xx 14 = P_2 xx 9# solve by dividing both side by 9

# 49 xx 14/9 = P_2# doing the math gives

76.222222 rounded off to 76 kPa.
