Remark
All numbers but two are not needed.
Step One
The cost of the insurance policy for 1 month is 66.60. Find 10% of the monthly cost.
Why ten %? The reason is that the other 90% is taken care of by his employer.
(10/100) * 66.60 = $6.66
Step Two
Find the yearly cost.
1 month = $6.66
12 months = x
1/12 = 6.66/x
x = 12 * 6.66
x = 79.92 <<<<< Answer
