The total cost of the television, the kettle and the juicer is $1080. The juicer costs twice as much as the kettle. The television costs thrice as much as the total price of the juicer and kettle. How much more does the juicer cost than the television?
| Juicer |
Kettle |
Television |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the kettle = 1 u
Cost of the juicer = 2 u
Total cost of the kettle and the juicer
= 1 u + 2 u
= 3 u
Cost of the television
= 3 x 3 u
= 9 u
Total cost of the juicer, the kettle and television
= 9 u + 1 u + 2 u
= 12 u
12 u = 1080
1 u = 1080 ÷ 12 = 90
Amount that the television cost more than the juicer
= 9 u - 2 u
= 7 u
= 7 x 90
= $630
Answer(s): $630
