Answer:
3,160,080
Step-by-step explanation:
- The first place can be taken by any one of the 22 students.
- The second place can be taken by any one of the remaining 21 students.
- The third place can be taken by any one of the remaining 20 students.
- The fourth place can be taken by any one of the remaining 19 students.
- The fifth place can be taken by any one of the remaining 18 students.
<em>This basically means multiplying 22, 21, 20, 19, and 18. Or, the number of permutation of 22 things taken 5 at a time.</em>
The answer is 22*21*20*19*18 = 3,160,080
<em>Using formula
</em>
Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.
