Answer:
£16
Step-by-step explanation:
Let's calculate the total amount saved by Grace over the three months.
Total saved = £9 (March) + £19 (April) + £11 (May)
Total saved = £39
Grace then spent £23 on a keyboard.
To find out how much money she has left, subtract the amount she spent from the total amount saved.
Money left = Total saved - Amount spent
Money left = £39 - £23
Money left = £16
