Family party

Anna has 5 €, Anezka has 4,60 € and for all the money they want to buy desserts for a family party. They decide between cakes and pinwheel: The pinwheel is € 0.40 more expensive than the cake, and the cakes can be bought for all the money by a third more than the pinwheels. How much does each dessert cost?

Correct answer:

t =  1.2
v =  1.6

Step-by-step explanation:


v=0.40+t
(5+4.60)v = (1+1/3)•(5+4.60)t

v=0.40+t
(5+4.60)•v = (1+1/3)•(5+4.60)•t

t-v = -0.4
38.4t-28.8v = 0

t = 6/5 = 1.2
v = 8/5 = 1.6
