Question 372477: The attendance at a scholol variety show was 578 people. A ticket for the lower box is worth 75 and a ticket for the upper box is worth 40. If the total revenue is 29,295,about how many tickets were sold for the lower box?
You can put this solution on YOUR website! lower box - x tickets --------------75 pesos
upper box -578-x tickets------------40 pesos
..
total collection = 29,295
..
75x+40(578-x)=29,295
75x+23,120-40x=29,295
35x+23120=29295
35x=29,295-23120
35x=6175
x=6175/35
x= 176 tickets
...
you can also set up a linear system
x+y = 578
75x+40y = 29295
