Dakota bought 120 ft of wire fencing at $0.50/ft to enclose a rectangular playground. The playground surface will be covered with mulch at a cost of $1.25/ft squared. Write a quadratic function that can be used to determine the total cost of fencing and mulch for a playground with side length x. What is the cost if one side is 20 ft?
