Answer:
9.83%
Explanation:
If the health insurance premium represents 9.83% of Barbara's income or less, it is considered affordable coverage. Only if it exceeds the 9.83% threshold, will Barbara be able to request a health insurance premium tax credit. Theoretically, if Barbara's health insurance was purchased in the Health Insurance Marketplace, the tax credit should be automatic and her premium should be lowered so that it can become affordable.
