one
From the first floor to the third floor, he actually took two stairs
So 22 * 2 = 44 steps
two
First year:
You can get 30000 yuan from company A
Get 15 + 1.6 = 31000 yuan in company B
2 * 12 = 24000 yuan in company C
Second year:
You can get 32000 yuan from company A
In company B, I got 17000 yuan plus 18000 yuan
Get (0.21 + 0.32) * 12 / 2 = 31800 yuan in company C
The third year:
You can get 34000 yuan from company A
In company B, I got 19000 yuan plus 29000 yuan
Get (0.33 + 0.44) * 12 / 2 = 46200 yuan in company C
Obviously, working in company C pays well (in the long run)
