The total cost of the dishwasher, the juicer and the blender is $400. The blender costs four times as much as the juicer. The dishwasher costs thrice as much as the total price of the blender and juicer. How much more does the blender cost than the dishwasher?
| Blender |
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 blender = 4 u
Total cost of the juicer and the blender
= 1 u + 4 u
= 5 u
Cost of the dishwasher
= 3 x 5 u
= 15 u
Total cost of the blender, the juicer and dishwasher
= 15 u + 1 u + 4 u
= 20 u
20 u = 400
1 u = 400 ÷ 20 = 20
Amount that the dishwasher cost more than the blender
= 15 u - 4 u
= 11 u
= 11 x 20
= $220
Answer(s): $220
