Answer: The answer is $ 59500.
Explanation: We must add the balance of cash and cash equivalents:
Currency and coins $ 12,500
Customer checks on hand $ 37000
Investment in 3-month U.S. Treasury bills $ 10,000
12500 + 37000 + 10000 = 59500.
Microsoft ordinary shares correspond to an investment that does not meet the characteristics of a short-term investment, since in that case if it were a short-term investment it would be considered a cash equivalent.
