Answer:

3 doughnuts for £2

Step-by-step explanation:

The first step is to determine how much we are paying per donut for each option.

For 3 doughts for £2, we should complete the following:

£2/3 = £0.67 per donut

For 5 doughnuts for £3.50, we should complete the following:

£3.50/5=£0.70 per donut

From these equations, we can see that we save £0.03 per donut if we buy them £2 for 3 donuts, making the grand total £10 for 15 donuts.
