Answer 1

Answer:£15.80

Step-by-step explanation: £4.40 for a 2-litre carton is the best buy since it is £2.20 for every litre.

So to fulfil the 7 litres for 7-days requirement the lowest price would be buying the best buys possible. Then it would be 3 2-litre cartons and 1 1-litre carton which would cost £15.80.
