The total cost of the computer, the hand blender and the toaster is $600. The toaster costs four times as much as the hand blender. The computer costs thrice as much as the total price of the toaster and hand blender. How much less does the toaster cost than the computer?
| Toaster |
Hand Blender |
Computer |
| 4 u |
1 u |
|
| 5 u |
15 u |
| 4 u |
1 u |
15 u |
Cost of the hand blender = 1 u
Cost of the toaster = 4 u
Total cost of the hand blender and the toaster
= 1 u + 4 u
= 5 u
Cost of the computer
= 3 x 5 u
= 15 u
Total cost of the toaster, the hand blender and computer
= 15 u + 1 u + 4 u
= 20 u
20 u = 600
1 u = 600 ÷ 20 = 30
Amount that the toaster cost less than the computer
= 15 u - 4 u
= 11 u
= 11 x 30
= $330
Answer(s): $330
