Answer:
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Step-by-step explanation:
Let
Number of students tickets sold = x
Number of adults tickets sold = y
x + y = 530 (1)
3x + 4y = 1740 (2)
From (1)
x = 530 - y
Substitute x = 530 - y into (2)
3x + 4y = 1740
3(530 - y) + 4y = 1740
1590 - 3y + 4y = 1740
- 3y + 4y = 1740 - 1590
y = 150
Substitute y = 150 into (1)
x + y = 530
x + 150 = 530
x = 530 - 150
x = 380
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets

Step-by-step explanation:
<u>First method</u>:
- Open Excel and enter 360, 353 and 346 in column A (below each other)
- Select all 3 cells and drag the bottom-right square down to row 40.
<u>Second method</u>:
- Use the equation t(n) = 360-7(n-1)
- Solve for n=40
- t(40) = 360 - 7*39 = 87
