You plan to put a fence around a rectangular lot. The length of the lot must be at
least 60 feet. The cost of the fence along the length of the lot is $1.50 per foot, and the
cost of the fence along the width is $2 per foot. The total cost cannot exceed $360.
a. Use two variables to write a system of inequalities that models the problem.
b. What is the maximum width of the lot if the length is 60 feet.
So, this is where I'm at..
x = length
y = width
1.5(2x) + 2(2y) ≤ 360
3x + 4y ≤ 360
{y ≤ 5/2x + 90
{x ≥ 60, y ≥ 0
x = 90, y...I went blank

At $15 per square foot the cost of installing flooring in a room with these dimensions is 7ft 5ft 8ft 12 ft
