Answer:
x ≥10 means the width (x) has to be greater than or equal to 10 feet
y ≥8 means the length (y) has to be greater than or equal to 8 feet
f = 2x + 2y means the fence has to have sides of the same length (x) and 2 sides of the same width (y)
3f ≤ 120 means that fencing (f) costs $3 per foot and needs to cost less than or equal to $120 (budget) which shows how many feet of fencing can be purchased
