The total cost of the computer, the kettle and the food processor is $1500. The food processor costs four times as much as the kettle. The computer costs twice as much as the total price of the food processor and kettle. How much more does the food processor cost than the computer?
| Food Processor |
Kettle |
Computer |
| 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 computer
= 2 x 5 u
= 10 u
Total cost of the food processor, the kettle and computer
= 10 u + 1 u + 4 u
= 15 u
15 u = 1500
1 u = 1500 ÷ 15 = 100
Amount that the computer cost more than the food processor
= 10 u - 4 u
= 6 u
= 6 x 100
= $600
Answer(s): $600
