The amount of money Candy started with after spending on drinks and cakes is £7.95
She bought a drink for £1.45 and a piece of cake for £1.20.
She has two thirds of here money left.
Let the money she has initially = x
Therefore,
2 / 3 x = x - 1.45 - 1.20
2 / 3 x = x - 2.65
subtract x from both sides
2 / 3 x - x = - 2.65
2x - 3x / 3 = - 2.65
- x / 3 = - 2.65
cross multiply
-x = - 2.65 × 3
- x = -7.95
x = £ 7.95
Therefore, Candy started with £7.95
