   Question 14.7 Notes
   
   In the answer when we calculate log.47 and get the final answer answer comes out to be 3.2% instead of 7.5% . Answer comes out to be 7.5 when we use ln.47 .
   
   Why are we using ln instead of log ?
   Question 15.8 Notes
   
   I dont understand why E(A3) is 1.1*[2+E(A2)] and rest 1.1*E[A(n-1)].

   In all of the CT subjects if it writes "log" it always means log base e, ie ln.
