Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT

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.
