The total cost of the laptop, the sandwich maker and the hand blender is $1200. The hand blender costs four times as much as the sandwich maker. The laptop costs twice as much as the total price of the hand blender and sandwich maker. How much less does the hand blender cost than the laptop?
| Hand Blender |
Sandwich Maker |
Laptop |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the sandwich maker = 1 u
Cost of the hand blender = 4 u
Total cost of the sandwich maker and the hand blender
= 1 u + 4 u
= 5 u
Cost of the laptop
= 2 x 5 u
= 10 u
Total cost of the hand blender, the sandwich maker and laptop
= 10 u + 1 u + 4 u
= 15 u
15 u = 1200
1 u = 1200 ÷ 15 = 80
Amount that the hand blender cost less than the laptop
= 10 u - 4 u
= 6 u
= 6 x 80
= $480
Answer(s): $480
