$1\mathrm{.}1$ Amplifier fundamentals

$1\mathrm{.}1$ A voltage amplifier of the type of Fig. $1\mathrm{.}1$ is fed by a $200-mV$ source and drives a $10-$ load. Voltmeter measurements give $v_{\text{I}}=150mV$ and $v_O=10V.$ If disconnecting the load causes $v_0$ to rise to $12$ V $,$ and then connecting a $30-k$ resistor across the input$-$port terminals causes $v_0$ to drop from $12$ V to $9\mathrm{.}6$ V $,$ find $R_s,R_i,A_{oc},$ and $R_0.$
