The number of tickets sold at a regular price is 20.
The linear equation:
an algebraic equation of the form y=mx + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Let x be the number of regular admission and y be the number of students.
The first statement is 48 tickets are sold. By this we get the first equation:
x + y = 48 ----------(1)
The second statement is the total collection for the ticket is $300. Form this we get the second equation:
8x + 5y = 300 --------(2)
Multiplying the equation by 5 we have:
5x + 5y = 240 --------(3)
Now subtracting equation (3) from (2) we get:
3x = 60
x = 20
Therefore we get that the ticket sold at regular price is 20.
