Equation 1 for tickets sold:
$35x + $25y = $10,250
Equation 2 for quantity (number #) of tickets sold:
x + y = 350
Use substitution method:
y = 350 - x
35x + 25 (350 - x) = $10,250
35x + $8750 - 25x = $10,250
10x + $8750 = $10,250
- $8,750 -$8,750
10x = 1,500
x = 150
y = 350 - 150
y = 200
Check the answers:
$35 (150) + $25 (200) =
$5,250 + $5,000 = $10,250
$35x + $25y = $10,250
Equation 2 for quantity (number #) of tickets sold:
x + y = 350
Use substitution method:
y = 350 - x
35x + 25 (350 - x) = $10,250
35x + $8750 - 25x = $10,250
10x + $8750 = $10,250
- $8,750 -$8,750
10x = 1,500
x = 150
y = 350 - 150
y = 200
Check the answers:
$35 (150) + $25 (200) =
$5,250 + $5,000 = $10,250

Answer:
- 150 lower level
- 200 upper level
Step-by-step explanation:
Let x represent the number of lower-level tickets sold. Then the total revenue is ...
35x +25(350-x) = 10250
10x +8750 = 10250 . . . simplify
10x = 1500 . . . . . . . . . subtract 8750
x = 150 . . . . . . . . . . . lower-level tickets sold
350-x = 200 . . . . . upper level tickets sold
There were 150 tickets sold for the lower level, and 200 sold for the upper level.
