Sure! Let's go through each question and explain how to find the answer.

1. Rate of inflation:
To find the rate of inflation, we need to use the formula:
Rate of Inflation = (CPI in Year 2 - CPI in Year 1) / CPI in Year 1

In this case, the CPI in 1991 is 246.8, and the CPI in 1992 is 362.4. Plugging these values into the formula, we have:
Rate of Inflation = (362.4 - 246.8) / 246.8

Now, let's calculate the answer:
Rate of Inflation = 0.469

Rounding to the nearest tenth, the answer is 0.5 (option 0.536).

2. Future value of an annuity due:
To find the future value of an annuity, we can use the formula:
Future Value = Payment * [(1 + r)^n - 1] / r

Where:
Payment = $450 (quarterly deposit)
r = 10% per year (compounded quarterly, so divide by 4)
n = 9 years (since quarterly deposits are made for 9 years)

Plugging these values into the formula, we have:
Future Value = $450 * [(1 + 0.10/4)^(4*9) - 1] / (0.10/4)

Now, let's calculate the answer:
Future Value ≈ $27,751.79

Therefore, the answer is $27,751.79 (option 4).

3. Depreciation expense using 150% declining balance method:
To calculate the depreciation expense, we can use the formula:
Depreciation Expense = (2 / useful life) * Book Value

The book value is the initial cost minus the accumulated depreciation. In the first year, the accumulated depreciation is zero, so the book value is equal to the initial cost.

Plugging in the values, we have:
Depreciation Expense = (2 / 4) * ($170,000 - $8,500)

Now, let's calculate the answer:
Depreciation Expense = $63,750

Therefore, the answer is $63,750 (option 1).
