A life insurance plan for Miss Cathleen

Cynthia helped Miss Cathleen while she was an intern with a life insurance company. Now, Miss Cathleen, aged 48, seeks for financial protection in case she would die around her retirement. To protect her growing-up children she wants to insure a benefit of 40,000 EUR for death between age 55 and 75, as shown below.

To value this temporary life insurance plan you will once again use the 1999 Belgian female life table, of which the one-year survival probabilities px and mortality rates qx have been preloaded. The assumed interest rate of 5% is available as i.
