Final answer:
The total debt ratio of Mobius, Incorporated is 0.7692 or 76.92%.
Step-by-step explanation:
The total debt ratio of Mobius, Incorporated can be calculated by dividing the total debt by the total assets. The total debt consists of bonds and loans, so it is the sum of their values which is 50 + 50 = 100. The total assets consist of reserves, bonds, and loans, so it is the sum of their values which is 30 + 50 + 50 = 130.
Therefore, the total debt ratio is 100/130 = 0.7692 (rounded to four decimal places) or 76.92%.
