To find: Number of student tickets sold.
Answer to Problem 2P
617 student tickets were sold.
Explanation of Solution
Given information:
Each adult ticket costs $4.
Each student ticket costs $2.
Total 920 tickets sold for $2446.
Calculations:
Let the number of student tickets be s .
Then
Number | Price ($) | Cost | |
Adult | 920 − s | 4.00 | 4(920 − s ) |
Student | s | 2.00 | 2s |
Now,
Adult tickets cost + Student tickets cost = Total tickets cost
Thus,
That becomes
Add 2s to both sides:
Subtract 2446 from both sides:
Divide the above Eq. by 2
Thus,
The numbers of student tickets sold were 617.
