<p>… I think there’s a mistake in the first line of the math? ie. where you have lin/(lapp + oapp), you correctly replace the denominator with (lin + oin)/0.09, but you put lin/0.3 in the numerator, where it should be lapp/0.3. I think?</p>
<p>EDIT: sorry, I meant lapp*0.3. actually, aren’t we trying to find lapp/(lapp + oapp), not lin/(lapp + oapp)?</p>
<p>EDIT#2… I think I still get 0.046 this way…</p>
