n-m=12a m=0.05n a/4=24 更新: how to do?
n-m=12a -------(1) m=0.05n --------(2) a/4=24 ---------(3) From (3): a = 96 sub a=96 into (1): n-m = 1152 -----(4) sub(2) into (4): n-0.05n = 1152 0.95n = 1152 n = 1212.63 from (2): m =0.05n =0.05(1212.63)=60.63
其他解答:
first: a=24x4=96 second: n-0.05n=12(96) 0.95n=1152 n=23040/19 third : m=0.05(23040/19)=1152/19|||||n-m=12a m=0.05n a/4=24 n-0.05n=12a a/4=24 0.95n=12a a=24X4 0.95n=12X96 a=96 0.95n=1152 n=1212.631578947 n=1212.63|||||a/4 = 24 a = 96 m = 0.05n n = 20m n - m = 12a 20m - m = 12(96) 21m = 1152 m = 54.86 n = 20 (54.86) n = 1097.2 2007-12-14 23:34:57 補充： 中間計錯了, 應該是:n - m = 12a20m - m = 12(96)19m = 1152m = 60.63n = 20 (60.63)n = 1212.6|||||n-m=12(96) n-m=1152 n=1152+m n=1152+0.05n 係咪真係計到 ga ?
