同学您好,
1、depreciation of each year under sun-of-the-year-digits methods(年数总和法下计算折旧):
1st year:(200000-20000)*5/(1+2+3+4+5)=180000*5/15=$60000
2nd year:180000*4/15=$48000
3rd year:180000*3/15=$36000
4th year:180000*2/15=$24000
5th year:180000*1/15=$12000
double decling balance method(双倍余额递减法下计提折旧):
1st:200000*2/5=$80000
2nd:(200000-80000)*2/5=$48000
3rd:(200000-80000-48000)*2/5=$28800
4th:(200000-80000-48000-28800-20000)/2=$11600
5th:(200000-80000-48000-28800-20000)/2=$11600
