Answer:
22
Step-by-step explanation:
So, first, we can find out how many home runs the coach hits in one game
So, 18 home runs in 9 games, so we can do 18 ÷ 9=2
So, he hits 2 home runs per game
But, we have to find for 11 games
So, we do 2*11(Runs times number of games) and get 22
Hope this clarified
