老師好,請(qǐng)問這個(gè)60*(P/F,8%,8)-60*(P/F,8%,1)等于608(P/F,8%,7)嗎



不等于,計(jì)算方法如下:
60 * (P/F, 8%, 8) - 60 * (P/F, 8%, 1) = (60 * 8%) * (1 + 8 + 64 + 512) - (60 * 8%) * (1 + 8) = (60 * 8%) * 579 = 69120
而608 (P/F, 8%, 7) = (608 * 8%) * (1 + 8 + 64) = 49152,
所以60 * (P/F, 8%, 8) - 60 * (P/F, 8%, 1) ≠ 608 (P/F, 8%, 7)
