The medical assistant salary is one of the best when it comes to the amount of education and training involved in preparing for the job. After earning only a certificate from a medical assisting program, graduates earn an average of almost $30,000 a year.
The average cost for a general liability insurance for a restaurant  varies between $1,700 and $10,000 per year. Pricing varies based on  the size and location of the restau â¦ rant.
Therefore $21,000= (1 â .56 which is the average variable cost ratio) Times Sales. Therefore $21,000 = .44 of Sales. Therefore $21,000/.44 = Sales (Divide both sides by .44) Therefore the Restaurant Needs $47,727 of Sales to Cover $21,000 of Fixed Costs.
