The company's income is $258 from each insured customer.


The company's expenses are  %281%2F3%29%2A110 + 0.8%2A95  for each insured customer.


So, the expected value for the company of each insured customer is


    258 - %281%2F3%29%2A110 - 0.8%2A95 = 145.33 dollars.


It is not exactly the figure from your list, but it is close to answer b).
