My Solution ( Method 1)

- 3 pumpkins = 24 ,

**Therefore , 1 pumpkin will represent 8 . ( 24/3 = 8)**

2 umbrellas + 1 pumpkin = 12

- Since 1 pumpkin represents 8,
- 12-8=4 -> (2 umbrellas + 1 pumpkin) - 1 pumpkin = 2 umbrellas
- 2 umbrellas represents 4.
**Therefore , 1 umbrella represents 2 . ( 4/2 = 2)**

- Since 1 pumpkin represents 8 ,
- 20-8=12 -> (2 starfishes + 1 pumpkin) - 1 pumpkin = 2 starfishes
- 2 starfishes represents 12
**Therefore 1 starfish represent 6. ( 12/2 = 6)**

Let p represents pumpkin

Let u represents umbrella

Let s represents starfish

- 3p = 24

- p = 24/3

- Therefore, p = 8

- Since 2p+u = 18
- 2(8)+u = 18
- 16+u = 18
- u = 18-16
- Therefore , u = 2

- Since p+2s = 20
- 8+2s = 20
- 2s = 20-8
- 2s = 12
- s = 12/2
- Therefore, s = 6
