On one production line in a small custom chip factory, marginal costs decrease rapidly as more chips are made. The marginal cost of making x thousand chips in a day is thought to be C'(x)=40 / the square root of x in hundreds of dollars. Given that it costs 40,000 dollars to make one thousand chips, find the cost of making 16 thousand chips in a day. Total cost in hundreds would be?
