Exercise 37

Your state has recently decided to install an RFID system for its toll roads. The current plan is to sell nonrefundable transponders for $20 and allow users to deposit up to $1,000 in their accounts. To assist the IT personnel, the system's planners want to develop a list of possible accounting transactions and system responses. Using your skills from earlier accounting classes, what debit and credit entries would you make for each of the following activities? (Feel free to develop your own accounts for this problem.)
a. A user buys a new transponder for $20.
b. A user adds $100 to his account.
c. A user discovers that a data entry clerk charges his credit card $1,000 instead of $100 when adding $100 to his account.
d. An individual leaves the state, turns in his transponder, and wants a cash refund for the $25.75 remaining in his account.
e. A good Samaritan turns in a transponder that he finds on the side of the road. There is a $10 reward for this act, taken from the owner's account.
