The fully covered premium amounts to $4,668. Next, we calculate the partially covered premium using:
25% * 9,264 = 2,316
Now, the total annual premium paid by Mr. Henderson's employer is equivalent to the sum of the completely covered premium and partially covered premium. This is:
4,668 + 2,316
= $6,984 of the Henderson family's annual premium is covered by Mr. Henderson's employer
