Accounting is actually one of those course that punch in lots of numbers, and I think she may want to have the dedicated numpad in a 15"
If she go for 14", then she may need to have a external numpad (Logitech wireless ~ RM80 is very good), otherwise life will really be miserable

For her usage, i3 & HD4000 is more than enough.
Anyway, 14"

Use remaining budget to get RAM (4G stick ~ RM100, 8G stick ~ RM200), extend warranty (Dell, extend to 3 years next business day on site ~ RM250, very good in case laptop broke down during assignment time

), swap HDD for SSD (128G ~ RM300, 256G ~ RM600).
15'' is heavy for gal to carry. so i think 14'' is enough.
