The total cost of the notebook, the blender and the juicer is $450. The juicer costs four times as much as the blender. The notebook costs twice as much as the total price of the juicer and blender. How much more does the juicer cost than the notebook?
| Juicer |
Blender |
Notebook |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the blender = 1 u
Cost of the juicer = 4 u
Total cost of the blender and the juicer
= 1 u + 4 u
= 5 u
Cost of the notebook
= 2 x 5 u
= 10 u
Total cost of the juicer, the blender and notebook
= 10 u + 1 u + 4 u
= 15 u
15 u = 450
1 u = 450 ÷ 15 = 30
Amount that the notebook cost more than the juicer
= 10 u - 4 u
= 6 u
= 6 x 30
= $180
Answer(s): $180
