Answer:
Step-by-step explanation:
You want the number of $4 general admission and $3 student tickets sold if 181 tickets resulted in revenue of $628.
It is convenient to define g as the number of general admission tickets sold. Then (181 -g) is the number of student tickets sold, and revenue is ...
4g +3(181-g) = 628
Simplifying gives ...
g + 543 = 628
g = 85 . . . . . . . . . . . subtract 543
181 -85 = 96 . . . . . . student tickets sold
There were 85 general admission and 96 student tickets sold.
