The total cost of the laptop, the blender and the deep fryer is $1400. The deep fryer costs four times as much as the blender. The laptop costs thrice as much as the total price of the deep fryer and blender. How much less does the deep fryer cost than the laptop?
| Deep Fryer |
Blender |
Laptop |
| 4 u |
1 u |
|
| 5 u |
15 u |
| 4 u |
1 u |
15 u |
Cost of the blender = 1 u
Cost of the deep fryer = 4 u
Total cost of the blender and the deep fryer
= 1 u + 4 u
= 5 u
Cost of the laptop
= 3 x 5 u
= 15 u
Total cost of the deep fryer, the blender and laptop
= 15 u + 1 u + 4 u
= 20 u
20 u = 1400
1 u = 1400 ÷ 20 = 70
Amount that the deep fryer cost less than the laptop
= 15 u - 4 u
= 11 u
= 11 x 70
= $770
Answer(s): $770
