The total cost of the notebook, the juicer and the sandwich maker is $600. The sandwich maker costs twice as much as the juicer. The notebook costs thrice as much as the total price of the sandwich maker and juicer. How much more does the sandwich maker cost than the notebook?
| Sandwich Maker |
Juicer |
Notebook |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the juicer = 1 u
Cost of the sandwich maker = 2 u
Total cost of the juicer and the sandwich maker
= 1 u + 2 u
= 3 u
Cost of the notebook
= 3 x 3 u
= 9 u
Total cost of the sandwich maker, the juicer 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 sandwich maker
= 9 u - 2 u
= 7 u
= 7 x 50
= $350
Answer(s): $350
