You are building a walkway of uniform width around a 100 foot by 60 foot swimming pool. After completing the walkway, you want to put a fence along the outer edge of the walkway. You have 450 feet of fencing to enclose the walkway. What is the maximum width of the walkway? This question is from textbook McDougal Littell Algebra 2

let x=width of the walkway
then
2%28%28100%2B2x%29%2B%2860%2B2x%29%29=450
2%284x%2B160%29=450
4x%2B160=225
4x=65
x=16.25
