Diego is building a fence for a rectangular garden. It needs to be at least 10 feet wide
and at least 8 feet long. The fencing he uses costs $3 per foot. His budget is $120.
He wrote some inequalities to represent the constraints in this situation:..
f = 2x + 2y
x ≥ 10
y28
3f ≤ 120

a. Explain what each equation or inequality represents.
b. His mom says he should also include the inequality f> 0. Do you agree?
Explain your reasoning.
