The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. The function L(s) = 54 + 1.15s represents the labor cost for producing s scissors. Which expression correctly represents the manufacturing cost per scissors?

The fixed costs are spread across the number of scissors produced....

    the other cost is per unit

 

so EACH scissor costs   ( M(s) + L(s)  ) /s   = 279/s  + 1.80
