✔ 最佳答案
總成本 = $10000

花店的總收入
= $15 x 1600 + $3 x (2000 - 1600)
= $24000 + $3 x 400
= $24000 + $1200
= $25200

盈利率
= (收入 - 成本)/成本 x 100%
= ($25200 - $10000)/$10000 x 100%
= $15200 / $10000 x 100%
= 1.52 x 100%
= 152%//

成本是$10,000.

收入是 $15 x 1,600 + $3 x (2,000 – 1,600) = $25,200.
盈利是 $25,200 - $10,000 = $15,200.

所以盈利率是 $15,200 / $10,000 = 152%.

該花店的盈利率:
(1600x15)+(2000-1600x3)=25600
(25200-10000)x100%=152%

每枝賺7.6元。
計算方法︰[15*1600+3*(2000-1600)]/2000-5
參考: 自己
