The total cost of the washing machine, the speaker and the food processor is $360. The food processor costs thrice as much as the speaker. The washing machine costs twice as much as the total price of the food processor and speaker. How much more does the food processor cost than the washing machine?
| Food Processor |
Speaker |
Washing Machine |
| 3 u |
1 u |
|
| 4 u |
8 u |
| 3 u |
1 u |
8 u |
Cost of the speaker = 1 u
Cost of the food processor = 3 u
Total cost of the speaker and the food processor
= 1 u + 3 u
= 4 u
Cost of the washing machine
= 2 x 4 u
= 8 u
Total cost of the food processor, the speaker and washing machine
= 8 u + 1 u + 3 u
= 12 u
12 u = 360
1 u = 360 ÷ 12 = 30
Amount that the washing machine cost more than the food processor
= 8 u - 3 u
= 5 u
= 5 x 30
= $150
Answer(s): $150
