Altimeter reading temperature correction

Is there a more simple formula for calculating (cold weather)temperature error correction on a conventional altimeter. And lets not get into a debate about Radio Altimeters.
Question: ''On a 3'degree GS, OAT-25, OM crossing height 1760' feet, what will the altimeter indicate?'' No whizz-wheels please.
I came accross a rather complicated formula.

Correction = h(15-to)
273+to-5k(e+h)
(as fraction)
h = height above the facility
k = Standard lapse rate 0.00198вк C per foot
e = elevation
t = temperature
to= t + ke
