Yea multiply 3 formulas,just look at the denominators and numerators and use 3 that cancel each other out and get the formula for the one with the 13percent thing.
Acct1501 exam has been the easiest so far,Econ1101 was easy too,I just did both the choice answers without realising they were choices and ended up not having time for 7 marks I left earlier to come back at and write with time in the compulsory Question.FML.
Math 1151 now,the one which has ripped me apart.
Gonna start studying today.Cuz I haven't done one problem,throughout the semester.No wonder I'm below a fail.
