Answers:
If all non-defective sneakers were sold, that's 8/9 of 360 or 320 sneakers at $58 = $18,560. They paid $26/each for them, that's 26 x 320 = $8320. Subtract what they paid from what they paid: 18,560 - 8320 = $10,240.
Even easier (and a check) is that they made a profit of $32 on each pair (58-26), so it's simply 32 x 320 = $10,240.
Check!
THE ANSWER IS: $9200 of profit
I am 100000000....% sure!

IT IS NOT $10,240!!
The company still paid for 360 shoes, not 320!
HOW?
320 pairs left x 58 each = $18560 sales
360 pairs bought x 26 each = $9360 paid
18560 - 9360 = profit which is $9200!
$10,240
360 * 1/9 = 40 defective
320 * $58 = $18, 560
320 * $26 = $8,320
$18, 560 - $8,320 = $10,240 profit
$360*(1-1/9)*($58-$26) = $10,240.
I bet no one else solved it with only one equation. If you can figure out how this equation was set up, then you are learning and becoming a better problem solver. Don't take the easy way out. Think and strive for excellence.
Oh, and don't do drugs.
