Explanation:

Sarah is making use of the needs approach to determine how much life insurance to buy

The first step is to calculate the total amount of life insurance

Total amount of life insurance = Total needs - total assets

Total need = income needs + cash needs + special needs

= $140,000 + $30,000 + $100,000

= $270,000

Total assets= retirement plan + bank account + investment account

= $30,000 + $20,000 + $40,000

= $90,000

Total amount of life insurance = $270,000-$90,000

= $180,000

Since Sarah is covered by $50,000 group insurance by her employer then the additional life insurance that should be purchased can be calculated as follows

= $180,000 - $50,000

= $130,000
