    Answer:

    £2.3

    Step-by-step explanation:

    The potatoes will cost £2 * the number of packs, which is 2. So that will cost £4. Now we do the same for the carrots £3 * 3 = £9, and turnips 90p * 3 = 270 (£2.7). We add that altogether; £4 + £9 + £2.7 and get £15.7. So if she pays with a £20 note, we subtract £15.7 from £20 and get £2.3. So she will get £2.3. I hope this helped!
