The total cost of the notebook, the hand blender and the juicer is $600. The juicer costs twice as much as the hand blender. The notebook costs thrice as much as the total price of the juicer and hand blender. How much more does the juicer cost than the notebook?
| Juicer |
Hand Blender |
Notebook |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the hand blender = 1 u
Cost of the juicer = 2 u
Total cost of the hand blender and the juicer
= 1 u + 2 u
= 3 u
Cost of the notebook
= 3 x 3 u
= 9 u
Total cost of the juicer, the hand blender and notebook
= 9 u + 1 u + 2 u
= 12 u
12 u = 600
1 u = 600 ÷ 12 = 50
Amount that the notebook cost more than the juicer
= 9 u - 2 u
= 7 u
= 7 x 50
= $350
Answer(s): $350
