Pat can use up to 150 feet of fencing to put around a rectangular garden.
If the length of the garden is three times the width, which inequality can be used to find the maximum perimeter?
Let x be the width of the garden.
The length of the garden is 3x.
The perimeter of the garden is 2(x+3x)=8x.
The inequality that can be used to find the maximum perimeter is 8x<150 or 8x<=150.
