✔ 最佳答案
(5.9*2-10)/5.9*2*100%=(11.8-10)/11.8*100%
=1.8/11.8*100%
=15.3%(correct to 3 sig. figs)

10/(5.9x2)x100%
=10/11.8x100%
=100/118x100%
=5000/59
=84 44/59

The discount =
5.9 x 2 - 10 / 10 X 100%
=11.8 - 10 / 10 x 100%
=1.8 / 10 X 100%
=180/10%
=18%
5.9 x 2 - 10 / 10 X 100%
=11.8 - 10 / 10 x 100%
=1.8 / 10 X 100%
=180/10%
=18%
