on question A debt was entered as 0.01875 which the system rounded it up to 0.02; on Common equit I entered 0.10875 which the system rounded up to 0.11. The system then generated the WACC as 0.13, which is ALL incorrect. Then on question B for debt I entered 0.04250 and it rounded to 0.04, then on common equity I entered 0.08250 and it rounded it to 0.08 so WACC was generated automatically again to 0.12 which is ALL incorrect as well. PLEASE HELP!!
