The values given are the change in their account balance. We can identify this by the words "Louise's account shows a total change of," and the other values are also identified as "total change of." From here, we are able to rank the changes of values from least to greatest.
$28.69 < $56.84 < $89.12
The friend with the least change is the friend whose change in account balance was $28.69. This is Franklin. This logic is consistent for the other friends.
