✔ 最佳答案
1. 先以100%提高手錶的標價
標價 = $860*(1+100%) = $1720
再提供x%折扣
賣出價 = $1720*x%
1720*x% = 860(1+35%)
2x% = 1+35%
x% = 135%/2
x = 67.5% (6.75折)
2.
先以50%提高手錶的標價
標價 = $860*(1+50%) = $1290
再提供y%折扣
賣出價 = $1290*y%
1290*y% = 860(1+35%)
1.5*y% = 1+35%
y% = 135%/1.5
y = 90% (9折)

Let x be the % mark up. Therefore, the marked price = 860(1+x).
Let y be the % discount. therefore selling price = 860(1+x)(1-y).
Therefore, % profit =[ 860(1+x)(1-y) - 860]/860 = 0.35
(1+x)(1-y) - 1 = 0.35
(1+x)(1-y) = 1.35.
a) If x =0.5 (50%), y =1-1.35/1.5 = 1- 0.9 = 0.1 = 10%.
b) If x = 0.8(80%), y = 1-1.35/1.8 = 0.25 = 25% etc.
