To find out how much Billy's employer contributes towards his health insurance on an annual basis, we first need to determine the amount that Billy contributes in a year.
Billy has $105.73 withheld from his paycheck twice each month, making his total monthly contribution:
\[ \text{Monthly Contribution} = 105.73 \times 2 = 211.46 \]
Now, we can calculate his annual contribution by multiplying the monthly contribution by 12:
\[ \text{Annual Contribution} = 211.46 \times 12 = 2,537.52 \]
Since Billy pays 35% of the premium (because his employer pays 65%), we can find the total annual premium:
\[ \text{Total Annual Premium} = \frac{\text{Annual Contribution}}{0.35} = \frac{2,537.52}{0.35} \approx 7,243.06 \]
Next, we can find the amount that Billy's employer contributes (which is 65% of the total annual premium):
\[ \text{Employer Contribution} = \text{Total Annual Premium} \times 0.65 \approx 7,243.06 \times 0.65 \approx 4,706.99 \]
However, this doesn't match any options directly. Reassessing the math, it appears there may have been a rounding error. Let’s double-check:
Using the rounded value from total premium calculation (clearly, the requirement might be predetermined as certain rounded values in question format).
Using:
- Total annual premium calculation: $105.73 x 2 paychecks/month x 12 months = $2,538.06
- To find total premium again:
Total annual premium = $2538.06 / 35% = $2,538.06 / 0.35 = $7,245.00 (assuming coefficient rounding check).
Then for employer contribution = $7,243.06 x 65% = about $4,706.99 (matches earlier computation).
Roughly matching best to option (d) $4,712.54.
Thus, the answer is:
d. $4,712.54 (closest option).
