The total cost of the washing machine, the toaster and the food processor is $1500. The food processor costs four times as much as the toaster. The washing machine costs twice as much as the total price of the food processor and toaster. How much less does the food processor cost than the washing machine?
| Food Processor |
Toaster |
Washing Machine |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the toaster = 1 u
Cost of the food processor = 4 u
Total cost of the toaster and the food processor
= 1 u + 4 u
= 5 u
Cost of the washing machine
= 2 x 5 u
= 10 u
Total cost of the food processor, the toaster and washing machine
= 10 u + 1 u + 4 u
= 15 u
15 u = 1500
1 u = 1500 ÷ 15 = 100
Amount that the food processor cost less than the washing machine
= 10 u - 4 u
= 6 u
= 6 x 100
= $600
Answer(s): $600
