Answer:
$125 trillion
Explanation:
To maintain the current debt-to-GDP ratio of 20%, we can calculate the required GDP in 15 years using the following steps:
**Step 1:** Calculate the current GDP using the current debt and debt-to-GDP ratio:
Current Debt = $15 trillion
Debt-to-GDP Ratio = 20%
Current GDP = Current Debt / Debt-to-GDP Ratio
Current GDP = $15 trillion / 0.20 = $75 trillion
**Step 2:** Calculate the future debt using the expected increase in debt:
Future Debt = $25 trillion
**Step 3:** Calculate the required future GDP to maintain the current debt-to-GDP ratio:
Required Future GDP = Future Debt / Debt-to-GDP Ratio
Required Future GDP = $25 trillion / 0.20 = $125 trillion
Therefore, in order to maintain the current debt-to-GDP ratio of 20%, the country's GDP will need to be $125 trillion in 15 years.
