The total cost of the computer, the toaster and the deep fryer is $400. The deep fryer costs four times as much as the toaster. The computer costs thrice as much as the total price of the deep fryer and toaster. How much more does the deep fryer cost than the computer?
| Deep Fryer |
Toaster |
Computer |
| 4 u |
1 u |
|
| 5 u |
15 u |
| 4 u |
1 u |
15 u |
Cost of the toaster = 1 u
Cost of the deep fryer = 4 u
Total cost of the toaster and the deep fryer
= 1 u + 4 u
= 5 u
Cost of the computer
= 3 x 5 u
= 15 u
Total cost of the deep fryer, the toaster and computer
= 15 u + 1 u + 4 u
= 20 u
20 u = 400
1 u = 400 ÷ 20 = 20
Amount that the computer cost more than the deep fryer
= 15 u - 4 u
= 11 u
= 11 x 20
= $220
Answer(s): $220
