A transistor is used in common-emitter mode in an amplifier circuit. When a signal of $\displaystyle 10$ mV is added to the base-emitter voltage, the base current changes by $\displaystyle 10 \mu \mathrm{~A}$ and the collector current changes by $\displaystyle 1.5$ mA. The load resistance is $\displaystyle 5 \mathrm{k} \Omega$. The voltage gain of the transistor will be \_\_\_\_.
