Answer:
1721 regular seat tickets were sold.
Step-by-step explanation:
Let's call X the number of tickets for regular seats. The relationship between regular tickets sold and balcony tickets sold, is given by:
X + 241 = 1762
Transposing terms in the previous equation, you get:
X = 1762-241 = 1521. Therefore, 1721 regular seat tickets were sold.
