sry the answer is $40, nt $30.

solutions:
$20 x 7 = $140 (7 wallets)
$140 + $50 = $190 (wallets + $50)
$15.50 x 10 = $155 (10 shorts before discount)
$155 - $5 = $150 (after discount)
$190 - $150 = $40 (answer)

Gela

y the answer is 100?

Hmm..
I think what he do is correct.
I get the same answer as him when attempting the question.

i think eu 4gt add 1 thing..
buyer A pay buyer B $150 1st to get the 15 shorts.. [ important ]

Question : how much Does Buyer B nid to return buyer A .. if buyer B wanted to buy the 20 wallet le ..


they are both seller and buyer



Let say is $100
Swapping Rate:
A : B
$190 : $155

At 1st
B now gt 10shorts 0 cash
A GT $150 and 20 wallet


if A gib B $150 and get 10shorts
**
B will have $150 cash 0item
A will have 10 shorts & 20wallet*

if B give $100 and take 20 wallet from A

Everything is back to swapping
B will have $50 and 20 tEESs [ $190 ]
and A will have $100 and 10shorts [ $255] - $100 = $155 [not discount yet]
