With the 5p, 2p, 2p, 1p, is there any sum from 1 to 10p that we cannot make? And therefore what about up to 20p? And then how can we apply this knowledge to the whole question?

No there isn’t any sun you can’t make.it only says as above

Okay, so can you make 21p? And you now know that you can make any sum from 50 to 70p, so can you make 49p?

Yes the smallest amount would be 21p that I can’t make. 49p would be the largest amount I can’t make using these coins?
