The total cost of the dishwasher, the juicer and the food processor is $800. The food processor costs four times as much as the juicer. The dishwasher costs thrice as much as the total price of the food processor and juicer. How much more does the food processor cost than the dishwasher?
| Food Processor |
Juicer |
Dishwasher |
| 4 u |
1 u |
|
| 5 u |
15 u |
| 4 u |
1 u |
15 u |
Cost of the juicer = 1 u
Cost of the food processor = 4 u
Total cost of the juicer and the food processor
= 1 u + 4 u
= 5 u
Cost of the dishwasher
= 3 x 5 u
= 15 u
Total cost of the food processor, the juicer and dishwasher
= 15 u + 1 u + 4 u
= 20 u
20 u = 800
1 u = 800 ÷ 20 = 40
Amount that the dishwasher cost more than the food processor
= 15 u - 4 u
= 11 u
= 11 x 40
= $440
Answer(s): $440
