Question

Sam buys

2 boxes of eggs costing £1.30 each
1 bottle of juice costing £2.60
3 baguettes
He pays with a £10 note and gets a 90p change.
Sam works out the cost of one baguette as £1.70

Is he correct?

You must show your working out.

Answer 1

He is not correct

2 boxes of eggs =1.30+1.30=2.60

1 bottle of juice cost=£2.60

2.60+2.60=£5.20

£10.00-0.90p=£9.10

9.10-5.20=£3.90

3.90/3=£1.30

1.30+1.30+1.30=£3.90

5.20+3.90=£9.10
