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

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

    when x = 200: 500x + 5000 ------------ x 500(200) + 5000 100000 + 5000 105000 --------------- = --------------- = ------- 200 200 200 105000 1050 ------- = ------ = 525 200 2
