The total cost of the computer, the hand blender and the stand mixer is $960. The stand mixer costs twice as much as the hand blender. The computer costs thrice as much as the total price of the stand mixer and hand blender. How much more does the stand mixer cost than the computer?
| Stand Mixer |
Hand Blender |
Computer |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the hand blender = 1 u
Cost of the stand mixer = 2 u
Total cost of the hand blender and the stand mixer
= 1 u + 2 u
= 3 u
Cost of the computer
= 3 x 3 u
= 9 u
Total cost of the stand mixer, the hand blender and computer
= 9 u + 1 u + 2 u
= 12 u
12 u = 960
1 u = 960 ÷ 12 = 80
Amount that the computer cost more than the stand mixer
= 9 u - 2 u
= 7 u
= 7 x 80
= $560
Answer(s): $560
