How much would you expect to pay to have a 32' x 42' x 4" thick slab of concrete laid? - x sc

I know that the price of cement by region (I live in Charleston, South Carolina), but I wonder if anyone could, with experience in the placement of the concrete slab please give me an approx. Idea of the costs of this size? Thank you!
