L1 关于Interest Rates and Growth Rates 的问题

有问题请教大家．

２００７　Ｌ１　教材　p197

Example 5-17

Calculating a Growth Rate (1)

For 1998, Limited Brands, Inc., recorded net sales of $8436 million. For 2002, Limited Brands recorded net sales of $8445 million, only slightly higher than in 1998. Over the four-year period from the end of 1998 to the end of 2002, what was the rate of growth of Limited Brands' net sales?

答案是:-

g=(FV/PV)^1/N-1 = (8445/8426)^1/4-1 = 0.000267

我想请问的是．1998年的销售额和2002年的销售额，根本就是一个苹果一个桔子，没有任何联系，怎么可以放在一起比呢？

就算要比，那也应该把1998年的销售额变成2002的FV　然后和2002年的销售额比啊！

请各位高手指教．
