The total cost of the notebook, the slow cooker and the food processor is $1500. The food processor costs four times as much as the slow cooker. The notebook costs twice as much as the total price of the food processor and slow cooker. How much less does the food processor cost than the notebook?
| Food Processor |
Slow Cooker |
Notebook |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the slow cooker = 1 u
Cost of the food processor = 4 u
Total cost of the slow cooker and the food processor
= 1 u + 4 u
= 5 u
Cost of the notebook
= 2 x 5 u
= 10 u
Total cost of the food processor, the slow cooker and notebook
= 10 u + 1 u + 4 u
= 15 u
15 u = 1500
1 u = 1500 ÷ 15 = 100
Amount that the food processor cost less than the notebook
= 10 u - 4 u
= 6 u
= 6 x 100
= $600
Answer(s): $600
