amistre64 · Answer

$$C(x) = 500x +\frac{5000}{x}$$ is this the equation?

anonymous · Answer

no, C = 500x + 5000
            _______________
                   X

amistre64 · Answer

so we simply plug in 200 for x:

500(200) + 5000 = 100000 + 5000 = 105000

105000/2 = 52500

500(200) + 5000       100000 + 5000       105000
---------------  =  --------------- =  -------
         200                          200                     200
