The total cost of the laptop, the sandwich maker and the juicer is $1200. The juicer costs twice as much as the sandwich maker. The laptop costs thrice as much as the total price of the juicer and sandwich maker. How much more does the juicer cost than the laptop?
| Juicer |
Sandwich Maker |
Laptop |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the sandwich maker = 1 u
Cost of the juicer = 2 u
Total cost of the sandwich maker and the juicer
= 1 u + 2 u
= 3 u
Cost of the laptop
= 3 x 3 u
= 9 u
Total cost of the juicer, the sandwich maker and laptop
= 9 u + 1 u + 2 u
= 12 u
12 u = 1200
1 u = 1200 ÷ 12 = 100
Amount that the laptop cost more than the juicer
= 9 u - 2 u
= 7 u
= 7 x 100
= $700
Answer(s): $700
