A sweet puzzle I can't finish: Spend exactly £10 on exactly 14 sweets, given that...
I am trying to work out the answer to a puzzle. I must so exactly £10 on exactly 14 sweets. I must buy at least 1 of every sweet.
The sweets cost a£1.50 b£1 c£0.10 and d £0.05.
I need to find three answers but can only find 2.
I've found 5a+2b+3c+4d and 3a+5b+4c+2d.
I've found lots of £10 with 13 or 15 sweets and some £10.05 etc with 14. What am I missing in trying to figure this out please?
Is there a way I should be using to find the latest one?
