Answer:
15
Step-by-step explanation:
1. We know that Mike has 40 baseball cards total. We know that Tim has 5 less than half of the cards that Mike has.
2. First, we need to divide 40 (Mike's total amount of baseball cards) by 2 or multiply that by 1/2. That gives us 20 baseball cards.
3. Tim has 5 less than half of Mike's deck (20 baseball cards) so we have to take away 5 more cards. 20 - 5 = 15. Tim has 15 baseball cards.
