Answer:
- 35 same-day tickets
- 20 advance tickets
Explanation:
You want the number of $30 advance tickets and $35 same-day tickets sold, when a total of 55 tickets were sold for $1825.
Setup
Let s represent the number of same-day tickets sold. Then 55-s is the number of advance tickets sold, and total revenue is ...
35s +30(55 -s) = 1825
Solution
5s = 175 . . . . . . Simplify, subtract 1650
s = 35
55-s = 30
35 same-day and 30 advance tickets were sold.
