The daily cost to print x paperback scifi novels is Cx35x100
     The daily cost to print x paperback sci-fi novels is C(x)=3.5x+1000. Find and interpret the slope of C.  f(x)=mx+b  y=mx+b  C(x)=3.5x+1000 
  
  Solution
Given C(x) = 3.5x+1000.
Compare this equation with y=mx+b.
Here m is the slope of the equation and b is the y-intercept.
So the slope of C(x) is 3.5.
