The total cost of the refrigerator, the sandwich maker and the hand blender is $1080. The hand blender costs twice as much as the sandwich maker. The refrigerator costs thrice as much as the total price of the hand blender and sandwich maker. How much less does the hand blender cost than the refrigerator?
| Hand Blender |
Sandwich Maker |
Refrigerator |
| 2 u |
1 u |
|
| 3 u |
9 u |
| 2 u |
1 u |
9 u |
Cost of the sandwich maker = 1 u
Cost of the hand blender = 2 u
Total cost of the sandwich maker and the hand blender
= 1 u + 2 u
= 3 u
Cost of the refrigerator
= 3 x 3 u
= 9 u
Total cost of the hand blender, the sandwich maker and refrigerator
= 9 u + 1 u + 2 u
= 12 u
12 u = 1080
1 u = 1080 ÷ 12 = 90
Amount that the hand blender cost less than the refrigerator
= 9 u - 2 u
= 7 u
= 7 x 90
= $630
Answer(s): $630
