  1. 1.the answer is incorrect because 7 flowers you have to do 1.20×7=21.00 so the answer is wrong it isn’t 9.80.the answer is wrong he would not reserve 11.80 because you’ll have to do 21.00×3=13.00.
    2.the answer is true because he’ll reserve 3.50 because 1.20+1.20+1.20=3.60and then you’ll have to do 1.50+ 1.50=3.50 then you do 3.60+3.50=7.10.
    3.you can use more or less to make 12.50. £10 note and use 20p 30p and 10p. :)

    • 2. The answer is false because John would get £3.40 not £3.50.He spent 1.50+1.50 =3.00 for crisps and £1.20+£1.20+£1.20=£3.60 for cakes. So he spent 3.60+3.00=6.60 altogether. Therefore he should get 10.00-6.60=3.40.

      3. The answer is true. To make 12.50 you can have 1 £10.00 note+£2.00 coin + 50 p. :)

  2. John needed to pay £1.00 more.

    This is incorrect because 2 crisps packets cost £3.00 and 3 cakes cost £3.60 so you take away the £6.60 from £10 that will = £3.40

  3. This is wrong because 7 flowers do not cost £9.20 but it shud be £8.20.You will not get change hr will ask £5.20.
