The total cost of the dishwasher, the hand blender and the speaker is $1350. The speaker costs four times as much as the hand blender. The dishwasher costs twice as much as the total price of the speaker and hand blender. How much more does the speaker cost than the dishwasher?
| Speaker |
Hand Blender |
Dishwasher |
| 4 u |
1 u |
|
| 5 u |
10 u |
| 4 u |
1 u |
10 u |
Cost of the hand blender = 1 u
Cost of the speaker = 4 u
Total cost of the hand blender and the speaker
= 1 u + 4 u
= 5 u
Cost of the dishwasher
= 2 x 5 u
= 10 u
Total cost of the speaker, the hand blender and dishwasher
= 10 u + 1 u + 4 u
= 15 u
15 u = 1350
1 u = 1350 ÷ 15 = 90
Amount that the dishwasher cost more than the speaker
= 10 u - 4 u
= 6 u
= 6 x 90
= $540
Answer(s): $540
