题目详情
The original value of machine X is V dollors,while the original value of machine
Y is 2V dollars.Both machies depreciate in value at a constant rate of 10
percent of their origical value per year.Compare :A.The value of machine X
after 3 years B.The value of machine Y in 6 years
请问到底是哪种列法对,题目不是说每年的都应该降低“原始价格”的10%么,所以我觉得应该是这种列法:
A=V-0.1*V*3=0.7V,B=2V-0.1*2V*6=0.8V.
为什么大家都是 A:v(1-10%)^3 B:2v(1-10%)^6 列的,哪种对,
Y is 2V dollars.Both machies depreciate in value at a constant rate of 10
percent of their origical value per year.Compare :A.The value of machine X
after 3 years B.The value of machine Y in 6 years

答案和解析
我觉得你不对,以为原文说的是at a constant rate of 10 percent,显然是按比例缩减.所谓original value就是上一年减完这一年还没减的原价.
这是我的观点.
