Answer:
1) Let the price of 1 kg apple is x Let the price of 1 kg grapes is y
2) According to the question:
2x+y =240 ---(1)
After a month:
4x+2y =500 = 2x+y = 250-(I)
The Solution of the equations graphically.
• 2x+y =240
| x 150 | 10 |
y | 140 | 40 |
2x+y = 250
| x 150
| 100 |
Ty 1 150 | 50 |
The lines of the equations in both condition are parallel to each other.
