let j be 每部電腦的標價
j x 50% +j =每部電腦的標價
( j x 50% +j )x (1-25%) =盈利百分率
=25%
j x 50% +j =每部電腦的標價
( j x 50% +j )x (1-25%) =盈利百分率
=25%

假設C為成本
標價為C * 1.5 = 1.5C
售價為1.5C * 75% = 1.125C
盈利百分率為
(1.125C - C) / C * 100%
12.5%
標價為C * 1.5 = 1.5C
售價為1.5C * 75% = 1.125C
盈利百分率為
(1.125C - C) / C * 100%
12.5%

Let cost of computer = c
so marked price = c(1 + 50%) = 1.5c
For a discount of 25%, selling price = marked price (1 - 25%) = (1.5c)(0.75)
= 1.125c
So % profit = (selling price - cost)/cost x 100% = (1.125c - c)/c x 100%
= 12.5%.
so marked price = c(1 + 50%) = 1.5c
For a discount of 25%, selling price = marked price (1 - 25%) = (1.5c)(0.75)
= 1.125c
So % profit = (selling price - cost)/cost x 100% = (1.125c - c)/c x 100%
= 12.5%.
