Lena [83]

Answer:

270 tickets were sold
not needed: books per player, tickets per book

Step-by-step explanation:

(total revenue)/(revenue/ticket) = total tickets

$810/$3 = 270 . . . total tickets

None of the other numbers in the problem are needed: books per player (1), tickets per book (10).
