The total cost of the computer, the food processor and the muffin maker is $480. The muffin maker costs thrice as much as the food processor. The computer costs twice as much as the total price of the muffin maker and food processor. How much more does the muffin maker cost than the computer?
| Muffin Maker |
Food Processor |
Computer |
| 3 u |
1 u |
|
| 4 u |
8 u |
| 3 u |
1 u |
8 u |
Cost of the food processor = 1 u
Cost of the muffin maker = 3 u
Total cost of the food processor and the muffin maker
= 1 u + 3 u
= 4 u
Cost of the computer
= 2 x 4 u
= 8 u
Total cost of the muffin maker, the food processor and computer
= 8 u + 1 u + 3 u
= 12 u
12 u = 480
1 u = 480 ÷ 12 = 40
Amount that the computer cost more than the muffin maker
= 8 u - 3 u
= 5 u
= 5 x 40
= $200
Answer(s): $200
