Answer:
Anne Mullens committed embezzlement.
Step-by-step explanation:
Embezzlement is defined as misappropriation of funds by someone with whom funds have been entrusted.
It is a theft as the money does not belong to the perpetrator. The perpetrator is only entrusted with funds.
One of the conditions for embezzlement is an existence of a fiduciary (trust) relationship between parties.
In the given case, Anne Mullens pocketed $57 cash from recorded amount instead of recording 57$ customer's payment via check. Instead she included the customer's check in the money to be taken to bank.
This is embezzlement of funds by Anne.
