The total cost of the laptop, the kettle and the food processor is $750. The food processor costs four times as much as the kettle. The laptop costs twice as much as the total price of the food processor and kettle. How much more does the food processor cost than the laptop?
| Food Processor |
Kettle |
Laptop |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the kettle = 1 u
Cost of the food processor = 4 u
Total cost of the kettle and the food processor
= 1 u + 4 u
= 5 u
Cost of the laptop
= 2 x 5 u
= 10 u
Total cost of the food processor, the kettle and laptop
= 10 u + 1 u + 4 u
= 15 u
15 u = 750
1 u = 750 ÷ 15 = 50
Amount that the laptop cost more than the food processor
= 10 u - 4 u
= 6 u
= 6 x 50
= $300
Answer(s): $300
