If Edna's gross income should be deducted $121.04 per month for life insurance, then she should be deducted [tex]121.04*12=1452.48[/tex] in a year.
Since her boss covers 80%, she will only need to be deducted 20% for life insurance. Getting 20% of 1,452.48, we'll get:
[tex]1452.48*0.20=290.50[/tex]
ANSWER: $290.50 is deducted from Edna's gross income per year for life insurance.
