✔ 最佳答案
2a)Profit of each bags of 4 packets = 29.4 - 4x6 = 5.4
He has 200 / 4 = 50 bags
total profit = 5.4 x 50 = 270
principal = 200 x 6 = 1200
Profit % = 270 /1200 = 22.5%
2b)
Profit on first day = 20 x 5.4 = 108
Loss on first day = ( 50 - 20 ) x (23.2 - 24) = 30 x (-0.8)
= -24
Total Profit = 108 - 24 = 84
Profit % = 84 / 1200 = 7%

a) 200*29.4/4-6*200
=270
the profit is $270
b) (29.4*20+23.2*30)-6*200
-------------------------------------- * 100%
6*200
=7%
the profit is 7%

200 x 5 = 1200
200/4 x 29.4 = 1470
Profit = (1470 - 1200)/1200 x 100
= 270/1200 x 100
= 22.5%
20 x 29.4 = 588
(50-20) x 23.2 = 696
Total of sale = 588 + 696
= 1284
Profit = (1284 - 1200)/1200 x 100
= 84/1200 x 100
= 7%
200/4 x 29.4 = 1470
Profit = (1470 - 1200)/1200 x 100
= 270/1200 x 100
= 22.5%
20 x 29.4 = 588
(50-20) x 23.2 = 696
Total of sale = 588 + 696
= 1284
Profit = (1284 - 1200)/1200 x 100
= 84/1200 x 100
= 7%
