A high school basketball coach counted the number of points his team scored each game.

Points per game

Stem : 1,2,3,4,5,6,7,8,9,10.

Leaf : 2,4,0,0,0,5,1,4,8,0 0

How many games had exactly 100 points ?

There are 2 leaves with a value of 0, representing 20 and 30 as the last digit of the points. Therefore, there are 20 + 30 = 50 games that had a total score ending in 0. None of the other leaves represent a number that ends in 00, so there are no games with exactly 100 points. Answer: $\boxed{0}$.
