With her savings, Sara bought two books: a book for 5.5£ and a book for 6.5£. She gives a 20£ bill to the seller. How much change does she get back?
Let's be accurate as possible. Think before you answer.

To find out how much the saleswoman should return to her, we have to find out how much Sara spent in total.

She spent 5.

5£ + 6.

5£ = 12£.

So she gives 20£ and the cashier should keep 12£.

The cashier therefore returns the difference between these two sums: 20£ – 12£ = 8£.

.

Therefore, the answer is 8
