The total cost of the laptop, the sandwich maker and the slow cooker is $600. The slow cooker costs thrice as much as the sandwich maker. The laptop costs twice as much as the total price of the slow cooker and sandwich maker. How much more does the slow cooker cost than the laptop?
| Slow Cooker |
Sandwich Maker |
Laptop |
| 3 u |
1 u |
|
| 4 u |
8 u |
| 3 u |
1 u |
8 u |
Cost of the sandwich maker = 1 u
Cost of the slow cooker = 3 u
Total cost of the sandwich maker and the slow cooker
= 1 u + 3 u
= 4 u
Cost of the laptop
= 2 x 4 u
= 8 u
Total cost of the slow cooker, the sandwich maker and laptop
= 8 u + 1 u + 3 u
= 12 u
12 u = 600
1 u = 600 ÷ 12 = 50
Amount that the laptop cost more than the slow cooker
= 8 u - 3 u
= 5 u
= 5 x 50
= $250
Answer(s): $250
