Melany has to fence a 5000 feet square field with wire mesh. If one foot of wire mesh is sold at $30, and she had $120000, how many feet of the field will not be fenced?
How many feet of wire mesh can Melany buy? ** Since one-foot wire mesh is sold at $30, with $120000, Melany can buy $120000/$30 = <<120000/30=4000>>4000 feet of wire mesh.
How many feet of the field will not be fenced? ** If Melany has to fence 5000 feet of the field and has 4000 feet of wire mesh, she will not fence 5000-4000 = <<5000-4000=1000>>1000 feet of the field.
