✔ 最佳答案
地氈平均價=$16000 / 20 = $800(a)首12塊地氈的盈利百分率 = ( $1000 -$800 ) / $800 * 100%
= ( $200 / $ 800 ) * 100%
= 1/4 * 100%
= 25%
( b )餘下8塊地氈的虧蝕百分率= ( $800 -$600 ) / $800 * 100%
= ( $200 / $ 800 ) * 100%
= 1/4 * 100%
= 25%
( c )總盈利百分率 = ( $1000 * 12 + $600 * 8 - $16000 ) / $16000 * 100%
= ( $16800 - $16000 ) / $16000 * 100%
= $800 / $16000 * 100%
= 5%

每塊地氈成本 = 16000/20 = $800
a) (1000-800)/800 x 100% = +25%
b) (600-800)/800 x 100% = -25%
c) (1000x12 + 600x8 - 16000)/16000 x 100% = +5%
