Final answer:
The firm's long-term capital structure is approximately 5.3% long-term debt and 94.7% equity.
Step-by-step explanation:
To calculate the long-term capital structure for the firm, we need to determine the proportion of long-term debt and equity in the firm's total financing. The total long-term financing is the sum of long-term debt and total shareholders' equity, which is $200,000 + $3,600,000 = $3,800,000.
The long-term debt proportion is calculated as (long-term debt / total long-term financing) x 100 = ($200,000 / $3,800,000) x 100, which is approximately 5.26%. Conversely, the equity proportion is calculated as (total shareholders' equity / total long-term financing) x 100 = ($3,600,000 / $3,800,000) x 100, resulting in approximately 94.74%. Hence, the firm's long-term capital structure is approximately 5.3% long-term debt and 94.7% equity.
: The firm's long-term capital structure is about 5.3% long-term debt and 94.7% equity, which corresponds to option (B) in the question.
