Answer:

45 marbles

Step-by-step explanation:

Little Billy's marbles on 1/1/2003: 60 marbles

On Billy's best friend's birthday on 4/4/2003 Billy gave 15% to his best friend: 15% of 60 = 15/100 x 60 = 9 marbles

Marbles Billy lost: 6 marbles

Total marbles Billy had at the beginning of the year: 60 marbles

Marbles Billy lost or gave up: 6 + 9 = 15 marbles

Total marbles Billy has on 1/1/2004: 60-15 = 45 marbles.

Therefore, Billy had 45 marbles in his collection on 1/1/2004.
