The total cost of the washing machine, the water heater and the blender is $1080. The blender costs thrice as much as the water heater. The washing machine costs twice as much as the total price of the blender and water heater. How much more does the blender cost than the washing machine?
| Blender |
Water Heater |
Washing Machine |
| 3 u |
1 u |
|
| 4 u |
8 u |
| 3 u |
1 u |
8 u |
Cost of the water heater = 1 u
Cost of the blender = 3 u
Total cost of the water heater and the blender
= 1 u + 3 u
= 4 u
Cost of the washing machine
= 2 x 4 u
= 8 u
Total cost of the blender, the water heater and washing machine
= 8 u + 1 u + 3 u
= 12 u
12 u = 1080
1 u = 1080 ÷ 12 = 90
Amount that the washing machine cost more than the blender
= 8 u - 3 u
= 5 u
= 5 x 90
= $450
Answer(s): $450
