The total cost of the washing machine, the hand blender and the muffin maker is $480. The muffin maker costs twice as much as the hand blender. The washing machine costs thrice as much as the total price of the muffin maker and hand blender. How much more does the muffin maker cost than the washing machine?

Muffin Maker	Hand Blender	Washing Machine
2 u	1 u
3 u		9 u
2 u	1 u	9 u

Cost of the hand blender = 1 u
Cost of the muffin maker = 2 u

Total cost of the hand blender and the muffin maker
= 1 u + 2 u
= 3 u

Cost of the washing machine
= 3 x 3 u
= 9 u

Total cost of the muffin maker, the hand blender and washing machine
= 9 u + 1 u + 2 u
= 12 u

12 u = 480

1 u = 480 ÷ 12 = 40

Amount that the washing machine cost more than the muffin maker
= 9 u - 2 u
= 7 u
= 7 x 40
= $280

Answer(s): $280
