Hi there!

Let think talk about these clues we have right now...

Luke is x2 more than Lily.

Luce is 45 less candy than Lily since 3 times 15.

225 candys in total...

Let make a random guess...

Lily: 70

Luke: 140

Lucy: 35

Total: 245

Now we know that there must be a half candy since it’s a odd number at the end of that...

Lily: 67.5

Luke: 135

Lucy: 22.5

Total: 225

But we are asked for only Lucy...

So the answer to this problem is 22.5.
