Fubuki BPP28 Annuity figure

It is the annuity factor at 4.5% (the risk free rate) for 4 years (the length of the borrowing).

Ok thanks. I thought we were supposed to use tables and round. I am never sure. If we are mid calculation do we round or only round for an actual calculation? For example: let's say the cost of equity of something is 10.79% so when i discount i use 11% But let's say I am doing a WACC calculation with that same figure, now do i use 11 or 10.79? same with this answer, the 4.5% was used Thanks

Using the tables to the nearest % will usually still get full marks. Even if you lose marks you would probably only lose 1 mark. It depends how short of time you are - using the formula does not actually take many seconds.
