Marcus Robinson bought an older house and wants to put in a new concrete patio. The patio will be 24 feet long, 9 feet wide, and 3 inches thick. Concrete is measured by the cubic yard. One sack of dry cement mix costs $6.50, and it takes four sacks to mix up 1 cubic yard of concrete. How much will it cost Marcus to buy the cement? (Round your answer to the nearest cent.) $
