The total cost of the television, the kettle and the food processor is $1800. The food processor costs four times as much as the kettle. The television costs thrice as much as the total price of the food processor and kettle. How much more does the food processor cost than the television?
Food Processor |
Kettle |
Television |
4 u |
1 u |
|
5 u |
15 u |
4 u |
1 u |
15 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 television
= 3 x 5 u
= 15 u
Total cost of the food processor, the kettle and television
= 15 u + 1 u + 4 u
= 20 u
20 u = 1800
1 u = 1800 ÷ 20 = 90
Amount that the television cost more than the food processor
= 15 u - 4 u
= 11 u
= 11 x 90
= $990
Answer(s): $990
