Answer:
The number of student ticket sold is 40
Step-by-step explanation:
Given;
total number of tickets sold,= 56 tickets
total amount the tickets were sold, = $328.
cost of student tickets, = $5
cost of adult ticket, = $8
Let the number of student ticket sold = x
Let the number of adult ticket sold = y
To determine the number of student tickets sold, we will have the following equations;
x + y = 56 ------ equation (1)
5x + 8y = 328 -----equation (2)
from equation (1), y = 56 - x
Substitute the value of y in equation (2);
5x + 8y = 328
5x + 8(56 - x) = 328
5x + 448 - 8x = 328
5x - 8x = 328 - 448
- 3x = - 120
x = 120 / 3
x = 40
Therefore, the number of student ticket sold is 40
