Here's the armor formula that I always go grab from Wowwiki. I haven't actually tested it very extensively, but it seems like it should be close (it shows a bit under 32k armor for 75% versus level 70 and just under 36k armor for 75% versus level 73, which is about correct):
Levels 60+ DR% = Armor / (Armor+400+85*(MobLevel+4.5*(MobLevel-59)))
And, as was stated earlier, the damage mitigation displayed on your character screen is with respect to a same-level attacker, so that's the quick way to go. However, with the formula you could always do a differential to find the change in damage reduction for a change in armor... :)
