Question

Edwin goes to a restaurant with some friends.

Here are the meals they have

2 fish and chips at £9.25 each
1 chicken and chips at £9.50
1 roast lamb at £10.55
4 puddings at £4.55 each.

Edwin pays for the meals with three £20 notes.

How much change should Edwin get?

Answer 1

£2.75

Explanation:

2(9.25) + 1(9.50) + 1(10.55) + 4(4.55) = x

19.00 + 9.50 + 10.55 + 18.20 = x

28.50 + 28.75 = x

57.25

60 - 57.25 = 2.75

Answer 2

£3.25

Explanation:

£9.25×2+ £9.50+£10.55+£4×4.55

18.5+9.50+10.55+18.2

=£3.25
