✔ 最佳答案
$2112 * 5%=16
16 glasses are broken.
Then
320-16
=304
304 * $9.2
=2796.8
( 2796.8 -2112 / 2112 ) x 100%
=32.4% for profit

Cost = $2112
Each glass cost $2112/320 = $6.6
5% of them are broken, So
320*5% = 16 of them are broken
The rest are sold at $9.2 each
$9.2*(320-16) = $2796.8
Profit = $2796.8 - $2112 = $684.8
OR
Profit = $9.2*[320*(1-5%)] - $2112 = $684.8
Each glass cost $2112/320 = $6.6
5% of them are broken, So
320*5% = 16 of them are broken
The rest are sold at $9.2 each
$9.2*(320-16) = $2796.8
Profit = $2796.8 - $2112 = $684.8
OR
Profit = $9.2*[320*(1-5%)] - $2112 = $684.8

The cost : $2112
95% can sell (did not broken) : 320x0.95=304
Price at $9.2 each, all the 304 glasses can return : 304x$9.2=$2796.8
His profit : $2796.8-$2112=$684.8
% of profit : 684.8/2112x100%=32.42%
95% can sell (did not broken) : 320x0.95=304

5% of glasses are broken 320 X (1-5%)=304
sale prices is $9.2
$304 X $9.2 - $2112 = $684.8
the answer is profit $684.8
sale prices is $9.2
$304 X $9.2 - $2112 = $684.8
the answer is profit $684.8
