The total cost of the washing machine, the juicer and the kettle is $600. The kettle costs four times as much as the juicer. The washing machine costs twice as much as the total price of the kettle and juicer. How much more does the kettle cost than the washing machine?
| Kettle |
Juicer |
Washing Machine |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the juicer = 1 u
Cost of the kettle = 4 u
Total cost of the juicer and the kettle
= 1 u + 4 u
= 5 u
Cost of the washing machine
= 2 x 5 u
= 10 u
Total cost of the kettle, the juicer and washing machine
= 10 u + 1 u + 4 u
= 15 u
15 u = 600
1 u = 600 ÷ 15 = 40
Amount that the washing machine cost more than the kettle
= 10 u - 4 u
= 6 u
= 6 x 40
= $240
Answer(s): $240
