1."Are these the plates from Dellers I told you about?" asked John, inspecting the floral pattern. Betty replied, "I looked at those, but these are exactly the same except for price. They were at Haskins, and 14 pence each cheaper. I would've spend the exact same at Dellers, £13.65, but gotten two fewer plates for my money." How many did she buy?

11 plates at £1.04 each

13 plates at 84p each

15 plates at 91p each
