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? answer choices are a. 171 - 0.50s b. 279 + 1.80s c. 279 + 1.80s/s d. 171-0.50s/s

Option C. is the answer.

Step-by-step explanation:

Function that represents the material cost is M(s) = 225 + 0.65s

and function representing the labor cost is L(s) = 54 + 1.15s

We have to find the expression for manufacturing cost.

Since Manufacturing cost = Labor cost + Material cost

                                          = M(s) + L(s)

Now by replacing the values of M(s) and L(s)

Manufacturing cost = (225 + 0.65s) + (54 + 1.15s)

                                = (225 + 54) + (0.65s + 1.15s)

                                = 279 + 1.80s

Now manufacturing cost of one scissors =

Here manufacturing cost is = 279 + 1.80s

and Number of scissors manufactured = s

So Manufacturing cost per scissors =

Therefore, Option C is the answer.
