Final answer:
When a customer reaches the annual deductible, they will pay 25% for most brand-named drugs and 37% for generic drugs.
Step-by-step explanation:
When a customer reaches the annual deductible, they will pay 25% for most brand-named drugs and 37% for generic drugs. The deductible is the amount that individuals pay out of pocket for their prescription drug costs before the federal government starts covering a portion of the costs. In this case, the federal government pays 75% of the prescription drug costs up to a certain threshold.
