carys had some money. She brought a dirnk for £1.55 and a piece of cake for £1.30 she now has three-quarters of her money left. how much money did she have to start with?

Answer 1

£11.40

Explanation:

She spent £1.55 + £1.30 = £2.85.

Now she has 3/4 of the original amount.

That means she spent 1/4 of the original amount.

£2.85 is 1/4 of the original amount.

The original amount is 4 × £2.85.

She started with £11.40.

You can solve it by writing an equation.

She started with x.

x - 2.85 = 3x/4

x/4 = 2.85

x = 11.40
