The total cost of the refrigerator, the stand mixer and the blender is $600. The blender costs four times as much as the stand mixer. The refrigerator costs twice as much as the total price of the blender and stand mixer. How much more does the blender cost than the refrigerator?
| Blender |
Stand Mixer |
Refrigerator |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the stand mixer = 1 u
Cost of the blender = 4 u
Total cost of the stand mixer and the blender
= 1 u + 4 u
= 5 u
Cost of the refrigerator
= 2 x 5 u
= 10 u
Total cost of the blender, the stand mixer and refrigerator
= 10 u + 1 u + 4 u
= 15 u
15 u = 600
1 u = 600 ÷ 15 = 40
Amount that the refrigerator cost more than the blender
= 10 u - 4 u
= 6 u
= 6 x 40
= $240
Answer(s): $240
