Answer:
Step-by-step explanation:
Cheapstore:
500p divided by 10 equals 50p, multiplied by 2 gives 100p or £1
£4 corresponds to 600g
Superstore:
600g divided by 10 results in 60g, which when multiplied by 3 yields 180g, added to 600g
£5 equals 780g
600 divided by 4 amounts to 150g for each pound
780 divided by 5 results in 156g for each pound
The box from the Superstore offers the best value
