正確答案是12%
公式如下:
[(650-572)/650]x 100%
= (78/650) x 100%
= 0.12 x 100%
= 12%
驗證如下:
650 x 12% = 78 (爸爸原本一日人工$650,12%,即78元)
650-78 = 572
公式如下:
[(650-572)/650]x 100%
= (78/650) x 100%
= 0.12 x 100%
= 12%
驗證如下:
650 x 12% = 78 (爸爸原本一日人工$650,12%,即78元)
650-78 = 572

〔(新值-原值) / 原值〕 *100% =百份率變化
〔 (572 - 650) / 650 〕 *100% = -12% (負數即減少了)
所以爸爸每日人工減少了12%
〔 (572 - 650) / 650 〕 *100% = -12% (負數即減少了)
所以爸爸每日人工減少了12%
