easy to approximate in your head. Divide 80 not by 5, but by 6. That is 13 1/3. that's the amount of your raise. So 80 minus 13 1/3 is 66 2/3, your original pay. Check it, it works because 13 1/3 is 1/5th of 66 2/3, which is 20%. Elegant.

80/1.2 = 80/(6/5) = 80*5/6 = 400/6 = 66 + 4/6 = 66 + 2/3 = 66.6666667

It depends if "now" is the time after first year. Now might be 3rd of 4th year which will make it impossible to calculate the amount earned the first year as we don't know how much raise the person got the following years.

Another simple way to do this is that 80k is know 120% of original salary. So divide 80k with 120 and then multiply by 100 which is 66666.6667
