Answer: 14
Step-by-step explanation:
Given
Mr. Russo bought 42 tickets to a Broadway show
He gives 19 tickets to a friend and loses 9 tickets on his way
So, the number of remaining tickets is the subtraction of given and lost tickets from the total tickets i.e.
[tex]\Rightarrow 42-19-9\\\Rightarrow 14\ \text{tickets}[/tex]
So, Mr. Russo is left with 14 tickets.
