Final answer:
The ETR (Effective Tax Rate) per quarter can be calculated by dividing the income tax expense by the pre-tax income and multiplying by 100.
Step-by-step explanation:
The ETR (Effective Tax Rate) per quarter can be calculated by dividing the income tax expense by the pre-tax income and multiplying by 100. Let's calculate the ETR for each scenario:
- For scenario a, the ETR would be 1.4% ($400 / $400 x 100).
- For scenario b, the ETR would be 2.35% ($100 / $100 x 100).
- For scenario c, the ETR would be -3.37% ($200 / -$200 x 100).
- For scenario d, the ETR would be 4.35% ($700 / $700 x 100).
Therefore, the ETR per quarter for each scenario would be 1.4%, 2.35%, -3.37%, and 4.35% respectively.
