The total cost of the refrigerator, the hand blender and the stand mixer is $960. The stand mixer costs thrice as much as the hand blender. The refrigerator costs twice as much as the total price of the stand mixer and hand blender. How much less does the stand mixer cost than the refrigerator?
| Stand Mixer |
Hand Blender |
Refrigerator |
| 3 u |
1 u |
|
| 4 u |
8 u |
| 3 u |
1 u |
8 u |
Cost of the hand blender = 1 u
Cost of the stand mixer = 3 u
Total cost of the hand blender and the stand mixer
= 1 u + 3 u
= 4 u
Cost of the refrigerator
= 2 x 4 u
= 8 u
Total cost of the stand mixer, the hand blender and refrigerator
= 8 u + 1 u + 3 u
= 12 u
12 u = 960
1 u = 960 ÷ 12 = 80
Amount that the stand mixer cost less than the refrigerator
= 8 u - 3 u
= 5 u
= 5 x 80
= $400
Answer(s): $400
