Lan pays a semi annual premium of $750 for automobile insurance, a monthly premium of ?115 for health insurance, and an annual premium of 350 for life insurance. What is the monthly expense?

To find Lan's monthly expense for insurance, we need to convert each of the premiums to a monthly cost and then sum them up.

1. **Automobile Insurance:**
   - Semi-annual premium: $750
   - Monthly cost: $ \frac{750}{6} = 125 $ dollars per month.

2. **Health Insurance:**
   - Monthly premium: $115

3. **Life Insurance:**
   - Annual premium: $350
   - Monthly cost: $ \frac{350}{12} \approx 29.17 $ dollars per month.

Now, add up all the monthly costs:

\[
125 + 115 + 29.17 = 269.17
\]

So, Lan's total monthly expense for insurance is approximately **$269.17**.
