Jake Redding owns and operates a tire and auto repair shop named Jakes Jack'em and Fix'em Shop. During the current month, the following activities occurred:
1. The shop charged $8,500 for repair work done during the month. All but one of his customers paid in full. The one customer who had not yet paid owed Jake $500. Jake still has the car in the shop's parking lot and he intends to keep it until the customer pays the bill. The $500 is included in the $8,500.
2. The total cost of parts and oil purchased during the month was $2,900. Jake pays for the parts with cash, but the oil is purchased in bulk from a supplier on 30 days' credit. At the end of the month, he still owes $400 to this supplier.
3. The cost of the parts that were used in repair work during the month was $2,600.
4. Jake paid $750 monthly rent on the repair shop on the first day of the month, and since he had extra cash on hand at the end of the month he paid another $750 to cover the next month's rent.
5. On the 10th of the month, Jake paid the previous month's utility bills of $250. At the end of the month, he received this month's utility bills, totalling $230, which he intends to pay on the 10th of next month.
6. Jake paid a friend $500 for helping him in the repair shop, and also gave him a new set of tires from the shop's stockroom. These tires had cost Jake $300, and could have been sold to customers for $400.
7. Other expenses related to operating the repair shop for the month totalled $875. All of these were paid during the month, as well as $125 that was owed from the previous month.
8. During the last week of the month, a customer dropped off her vehicle for repair work. Jake set aside $600 of parts to be used in these repairs, but he has not yet had time to do any work on this job.
