each baseball team has 9 players and each football team has 11 players. 6 schools have both baseball and football teams. Four schools have only a baseball team. how many players are there for all 10 schools

156 players

Step-by-step explanation:

The 9 players for baseball and 11 players for football are added. 9 + 11 = 20.

Once you have 20, you can multiply it by the 6 schools. Which gets you 120 players so far.

After you multiply the 4 schools by the 9 players for baseball. You'll get 36. Add the 120 players to 36 players and you'll get 156 players for the 10 schools in total
