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
