This chart shows the total average monthly cost of medical insurance benefits for employees working in the private sector in mar
marusya05 [52]
It is given in this item that the subject of interest has to pay the single coverage for the medical insurance and is given to be equal to $322.77. 

Let x be the number of hours that a person should work in order to pay for the cost of the medical insurance. The value of this variable is calculated by dividing the total insurance cost by the amount that a person earns every hour.

                             x = $322.77 / ($10/hr)
                             x = 32.277 hours

Therefore, the number of hours that a person should work is equal to 32.277 which is approximately equal to 32 hours and 17 minutes.
