Question

Gwen has a £5 note and a £2 coin. A litre of cola costs £1.25. Gwen buys as many litre bottles of cola as she can. How much money will she have left over?

Answer 1

Gwen can buy 5 bottles of cola with her £7 and will have £0.75 left over.

Step-by-step explanation:

Gwen has in total £7 (£5 note + £2 coin). A litre of cola costs £1.25. To find out how many bottles of cola Gwen can buy, we need to divide the total amount Gwen has by the cost of one bottle of cola.

1. Divide the total amount of money (£7) by the cost of one litre of cola (£1.25).
2. £7 ÷ £1.25 = 5.6. Gwen can buy 5 bottles because she cannot buy a fraction of a bottle.
3. Multiply the number of bottles she can buy (5) by the cost per bottle (£1.25) to find out the total cost. 5 × £1.25 = £6.25.
4. Subtract the total cost of the cola (£6.25) from the total amount of money Gwen has (£7). £7 - £6.25 = £0.75.

Therefore, Gwen will have £0.75 left over after buying as many bottles of cola as she can.
