The total cost of the notebook, the stand mixer and the blender is $900. The blender costs four times as much as the stand mixer. The notebook costs twice as much as the total price of the blender and stand mixer. How much less does the blender cost than the notebook?
| Blender |
Stand Mixer |
Notebook |
| 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 notebook
= 2 x 5 u
= 10 u
Total cost of the blender, the stand mixer and notebook
= 10 u + 1 u + 4 u
= 15 u
15 u = 900
1 u = 900 ÷ 15 = 60
Amount that the blender cost less than the notebook
= 10 u - 4 u
= 6 u
= 6 x 60
= $360
Answer(s): $360
