The owner of a video store has determined that the cost C, in dollars, of operating the store is approximately given by where x is the number of videos rented daily. Find the lowest cost to the nearest dollar.

To find the lowest cost, we need to determine the minimum point on the cost function. However, the given function for the cost, C, is missing and was not provided. Please provide the correct function for the cost, including the missing part, so that I can assist you further.

given by what? Presumably some parabola.
