The total cost of the washing machine, the muffin maker and the food processor is $1350. The food processor costs four times as much as the muffin maker. The washing machine costs twice as much as the total price of the food processor and muffin maker. How much less does the food processor cost than the washing machine?
| Food Processor |
Muffin Maker |
Washing Machine |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the muffin maker = 1 u
Cost of the food processor = 4 u
Total cost of the muffin maker 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 muffin maker and washing machine
= 10 u + 1 u + 4 u
= 15 u
15 u = 1350
1 u = 1350 ÷ 15 = 90
Amount that the food processor cost less than the washing machine
= 10 u - 4 u
= 6 u
= 6 x 90
= $540
Answer(s): $540
