A company suspects that a fraud has been committed by one of its employees. The employee in question has been found to have submitted expense reports with fraudulent receipts. The company hired a forensic accountant to investigate the case. After analyzing the expense reports, the forensic accountant found that the average amount of the legitimate receipts submitted by the employee was $120, and the average amount of the fraudulent receipts was $250. The forensic accountant also found that the employee submitted a total of 30 receipts, and the total amount claimed was $4,500.

Assuming that the forensic accountant's findings are correct, answer the following questions:

a) What is the total amount of legitimate receipts submitted by the employee?
b) What is the total amount of fraudulent receipts submitted by the employee?
c) What percentage of the employee's claimed expenses were fraudulent?
d) If the company decides to take legal action against the employee and the court awards damages equal to three times the amount of the fraudulent receipts, what is the total amount of damages awarded to the company?
