Final answer:
The interest payments on South Pangean debt are $4 million, and the total expenditures with interest payments are $34 million.
Step-by-step explanation:
The student is dealing with a financial mathematics problem related to debt and interest payments.
Interest Payment Calculation
If South Pangean debt is $100 million at an interest rate of 4 percent, their yearly interest payment is calculated as:
(100,000,000 x 0.04) = $4 million.
So, the total interest payment must be $4 million.
Total Expenditures Calculation
With expenditures of $30 million without interest payments:
(30,000,000 + 4,000,000) = $34 million.
Therefore, the expenditures with interest payments would amount to $34 million.
