Maddix is planning to pour a concrete patio with the dimensions shown below. The company he plans to have deliver the concrete charges $145 per cubic yard, and there is a $100 delivery fee for each truckload. If the truck can haul up to 8 cubic yards of concrete each trip, how
much will the concrete cost to pour the patio?

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
