Answer:
Principal.
Explanation:
Principal is the amount that is borrowed when a person collects a loan. It is the amount that is paid back with interest during the life of the loan. Interest is the cost of the loan collected.
For example if one collects a loan of $100 with interest payment of 10%. They will pay back the principal ($100) and the interest ($10) that is $110.
The $30,000 that Pamela borrows is the principal amount. That she will payback with interest over the life of the loan.
