Celine, Jasper, Tori, Hunter L., and Will were running in a marathon.  These are the numbers they wore when they ran the marathon.

There are 600 runners in a marathon.  Each of the 600 runners were assigned a different number.  The runners were given their numbers in the order they signed up.  For example, the first person to sign up got 1, next got 2, and so on and so forth.

What number did each person wear?

Here are your clues:

• Of the group, Celine had the lowest number.
• The digit in the ones place on Hunter's shirt is 3 more than the digit in the ones place on Celine's shirt.
• Jasper was the last person to sign up.
• Will and Tori were the closest in line.
• If you add all of the digits on Will's shirt together, they total 18.
