Answer: B. (40,40)
Step-by-step explanation:
Given Inequalities:
(i) 3x + 8y ≤ 480
(ii) y - x ≤ 20
For first inequality:
(a) y intercept: (0, 60)
(b) x intercept: (160, 0)
- Plot this line with a solid line and shade below.
For second inequality:
(a) y intercept: (0, 20)
(b) x intercept: (-20, 0)
- Plot this line with a solid line and shade below.
The point (40, 40) falls between these two inequalities.
