$76. kPa$ $"76. kPa"$ .

Explanation:

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

$P_{1} \times V_{1} = P_{2} \times V_{2}$ $P_1xxV_1 = P_2 xx V_2$ substituting the given values gives

$49 \times 14 = P_{2} \times 9$ $49 xx 14 = P_2 xx 9$ solve by dividing both side by 9

$49 \times \frac{14}{9} = P_{2}$ $49 xx 14/9 = P_2$ doing the math gives

76.222222 rounded off to 76 kPa.
