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?
Thoughts? Step-by-step reasoning:
Since one - foot wire mesh is sold at $30, with $120000, Melany can buy $120000 / $30 = 4000 feet of wire mesh. If Melany has to fence 5000 feet of the field and has 4000 feet of wire mesh, she will not fence 5000 - 4000 = 1000 feet of the field.
Thus, the answer is 1000.
