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.
