Step-by-step explanation:
The percentage of the premium cost that Barbara is expected to contribute toward the premium is determined by her household income in relation to the federal poverty line. If her household income in 2022 is 150% of the federal poverty line, then she is expected to contribute a percentage of the premium cost that falls within the range of 100-400% of the federal poverty line.
The percentage of the premium cost that an individual is expected to contribute is determined by their household income as a percentage of the federal poverty line, as well as the cost of the benchmark plan. The ACA marketplace uses a sliding scale to determine the percentage of the premium cost that an individual is expected to contribute. The sliding scale ranges from 2% for individuals with a household income at 100% of the federal poverty line, to 9.78% for individuals with a household income at 400% of the federal poverty line.
So, in order to determine the percentage of the premium cost that Barbara is expected to contribute, we would need to know her household income as a percentage of the federal poverty line and the cost of the benchmark plan. Without this information, it is not possible to accurately determine her expected contribution toward the premium.
