發問:

小斗以450元購入一箱芒果.84個芒果中有18個爛了,他將好的芒果每個以8元出售.求小斗的盈利百分率或虧蝕百分率.

最佳解答:

Answer is 17.3% because first you have to find out how many good mangos are there so total (84) - bad (18) = 66 (good) Then you multiply by 8 because then u get what u earn from those 66 dollars 66 (good) * 8 = 528 (what you have earn) Subtract the cost that you bought the mango 528 - 450 = 78 to work out the percentage of the 盈利 78/450 = 0.17333333 then *100 to get percentage so the percentage is 17.3%

其他解答:

盈利=(8*(84-18))-450 =(8x66)-450 =528-450 =78 盈利百分率=(78/450)x100% =17.33%|||||(84-18)x8-450 ____________x100% 450 =17.33333333% 盈利百分率係17.33333333%B5117735D6B60D95
