Question

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 1

We have the function \(M(s)=225+0.65s\) and\(\sf\ s= scissors\) and the function \(L(s) = 54 + 1.15s\) which represents the labor cost for producing s scissors and again, \(\sf s=scissors\). Meaning that \(\bf M(s)+L(s)\).

Answer 2

So what we have to do is \[M(s)+L(s)=\]\[225+0.65s+54+1.15s=\]\[279+1.8s=\]Total cost of \(\it s\) \(\bf (s=scissors)\) = \(279+1.8s\) Meaning \(\frac{279+1.8s}{s}\) is the `manufacturing cost per scissors`
