How much life insurance do you need? Calculating needs $-$ Part$1$

Patrick and Stasia Strong are $38$ years old and have one daughter, age $9.$ Patrick is the primary earner, making $$140,000$ per year. Stasia does not currently work. The Strongs have decided to use the needs analysis method to calculate the value of a life insurance policy that would provide for Stasia and their daughter in the event of Patrick's death.

Patrick and Stasia estimate that while their daughter is still living at home, monthly living expenses for Stasia and their child will be about $$4,000($in current dollars$).$ After their daughter leaves for college in $9$ years, Stasia will need a monthly income of $$3,300$ until she retires at age $65.$ The Strongs estimate Stasia's living expenses after $65$ will only be $$2,900$ a month. The life expectancy of a woman Stasia's age is $87$ years, so the Strong family calculates that Stasia will spend about $22$ years in retirement.
