If I remember correctly, it should be something from technical economics. 1 I use the "equal payment sinking fund formula". When i = 6%, in the case of 5 years, I use F (A/F, i, n) =

0.1774*200000=35480 yuan/year 2 is the "equal payment capital recovery formula" which is P (A/P, i, n)=0.2013*200000=40260 yuan/year 3 The 120,000 here should be regarded as F

Bar?

I won’t be wordy~ F (A/F, i, n) = 0.1363*120000 = 16356 yuan/year~
