A Fast Food Restaurant Just Leased a New Freezer and Food

question 3

Essay

A fast food restaurant just leased a new freezer and food fryer for three years. The service contract for the freezer offers unlimited repairs for a fee of $125 a year plus a $35 service charge for each repair needed. The restaurant’s research suggested that during a given year 80% of these freezers need no repairs, 11% needed to be serviced once, 5% twice, 4% three times, and none required more than three repairs.
-How many times should the restaurant expect to have to get this freezer repaired over the three-year term of the lease?
