Bill's fence problem, budget is $500. he can have a max height of 7 feet, how much can bill buy if 3 feet tall cost-$13.81, 4ft tall cost $15.44, 5 feet tall cost $16.88, 6 feet tall cost $20.36, 7 feet tall cost $24.78, and 8 feet tall cost $28.15. i am if the fence can't be but a max of 7 feet then bill only needs to buy the 7 feet tall panel and he will have $ left over.
