Answer:
Explanation:
You can set a system of two equations.
1. Variables
2. Cost
x + 0.5y = 220 ↔ equation (1)
3. There were 80 more pencils than pens
Then:
pencils = 80 + pens
↓ ↓
y = 80 + x ↔ equation (2)
4. Solve the system
i) Substitute the equation (2) into the equation (1):
ii) Solve
iii) Substitute x = 120 into the equation (2)
Solution: 120 pens and 200 pencils ← answer
B) The system has exactly 2 solutions.
C) The system has infinitely many solutions.
